Just Color Picker

Free portable colour picker and colour editor for web designers and digital artists.

Just Color Picker main window, compact mode Graphic designers, digital artists and web-designers tend to look at things differently. They see the arrangement and colour scheme of things that mere mortals would just take for granted. Anything can be a piece of art or an inspiration, but it takes a discerning eye to really see it sometimes. While taking part in any computer routine, designers may see colours and colour combinations that they would like to use in their projects. With Just Color Picker, identifying the colours, saving, editing and combining them into beautiful colour combinations is a quick and simple job.

One of the main advantages of Just Color Picker is that it was created by a person who uses it on an everyday basis. It is a software for designers and digital artists created by a designer and digital artist.

Just Color Picker features:

  • Five formats of colour codes: HTML, RGB, HEX, HSB/HSV, HSL and CMYK.
  • Averaged colour sampling for easy handling of colour noise.
  • 3x, 9x and 15x magnifier and keyboard control of the mouse cursor movements for greater precision.
  • Colour list for saving and reusing the picked colour samples.

  • Red-Green-Blue (RGB), Cyan-Magenta-Yellow (CMY) and Red-Yellow-Blue (RYB) colour wheels with marked triads and complementary colours.
  • Harmonious colour scheme generator. With this feature you can quickly find a good combination of colours, for example, for your web site. Simply choose the primary colour of your design, and the colour picker will offer a few colours harmoniously matching with it.
  • RGB, HSV and HSL colour editors for adjusting and editing the picked colours.
  • Gradient transition between the two latest-picked colours for creating a wide range of in-between hues.
  • Text tool for evaluating the readability of the selected font and background colour combinations.

Online Manual

Main window (Compact mode)

Just Color Picker main window, compact mode Just Color Picker is a tool that captures the colour of any pixel in any screen area and displays its code in a variety of formats: HTML, RGB, HEX, HSB/HSV, HSL and CMYK.

To pick a colour and its code, choose the desired format in the colour code formats list, then point the mouse cursor at the pixel or screen area and press the hotkey to capture this colour. The default hotkey combination is Alt+X.

To copy the code of the colour to the clipboard, click the Copy Value button. The Copy Value button copies the whole content of the colour code field, or its selected part if you selected a part of the code beforehand.

Colour list

All the colours you have picked since you launched the program are displayed in the colour list.

To select a colour in the list, simply click the colour line in the list. This will make the colour active and its colour code will be displayed in the colour code field ready to be copied or edited. A right-click on a selected colour line in the list will allow you to copy the colour code to clipboard, add/edit a comment for the colour, or delete the colour from the list. You can also delete a colour from the list by selecting it with a left-click and then pressing the Delete key.

Main window extension (Extended mode)

Just Color Picker main window, extended mode, with comments The button with up/down arrows (next to the Copy Value button) expands the program window and opens the RGB/HSV/HSL colour editor, gradient field and harmonious colour finder.

The RGB/HSV/HSL colour editor contains the latest-picked colour or the selected colour, which you can modify and then pick the resulting colour for your further needs. Use the RGB mode to change red, green or blue components of the colour. Switch to HSV or HSL modes if you need to change the colour’s hue, saturation, or value or lightness.

The harmonious colour scheme generator suggests a few colours that may be a good combination with the latest-picked, selected or being-edited colour. These colours are merely a suggestion, and the final decision about the best colour combination is of course up to you.

The gradient feature provides you with a wide range of nuances and gradations between the two latest picked or selected colours, in case you need to get something in-between.

Code-to-Colour conversion

For the inverse process of conversion of colour codes into the corresponding colours, enter the colour code into the colour code field and press Enter. The colour will appear in the colour list and its code will stay in the colour code field, in exactly the same way as if you picked it with the mouse from your screen.

Just Color Picker can convert HTML, HEX and RGB codes into colours:

  • To convert an HTML code, enter the six-character colour code with or without the preceding # symbol and press Enter.
  • To convert a HEX code, enter the six-character colour code with or without the preceding 0x symbols and press Enter.
  • To convert an RGB code, enter the three digital parts of the colour code (from 0 to 255) separating the parts with commas and/or spaces and press Enter.

If Just Color Picker does not display the colour after you pressed Enter, it means the colour code has been entered incorrectly. Correct the input and press Enter again.

Main menu


There is a 3x, 9x and 15x zoom of the mouse cursor area. Use the Zoom menu item to change zoom magnification or to switch it off.

Colour Sample Area menu item offers an option for picking either the exact colour of a single pixel, or an average colour value of 3 by 3 or 5 by 5 pixel area with the pointed pixel in the centre of the area. When the 3 by 3 Average or 5 by 5 Average option is chosen, a grey rectangle bounding the averaged area will appear in the zoom field, and a “3x3 Avg” or “5x5 Avg” label will be shown in the current colour area.

To change the hotkey, go to the Hotkeys menu item. Select a new hotkey combination by pressing the keys (will be displayed in the window), then click OK. Be careful: do not choose a combination that is already assigned to another program, as the combinations will clash and may not work correctly in either of the programs.

Enabling the Stay on Top feature will keep Just Color Picker window over all other programs until you close or minimize it.

Show # in HTML code option shows or hides the hash symbol in HTML colour codes.


In contains the Colour Wheels and Text tools.

Red-Yellow-Blue (RYB) colour wheelColour Wheels

The Colour Wheels tool displays RGB (Red, Green, Blue), which is also CMY (Cyan, Magenta, Yellow), and RYB (Red, Yellow, Blue) colour wheels for the latest-picked or selected colour. The colour wheels have the selected colour, triads and complementary colours marked, and contain as many colours as defined in the Number of Colours option. You can open any number of wheel windows to compare the colours. Please note that white, black and shades of neutral grey technically are not colours; they do not have saturation, and, therefore, they cannot generate a corresponding colour wheel.

RGB colour circle can be used for finding harmonious colour combinations within additive colour model and digital output devices like computer screens. RYB colour circle is used for working with colour mixing and colour harmony in subtractive colour model, which is a classical theory of colour vision and pigment mixing still widely implemented in fine art, particularly in painting.

Just Color Picker text tool Text

The Text tool helps to find out whether a particular combination of font colour and background colour is going to look good and be easy to read. The tool becomes available whenever you picked two or more colours. It offers a comprehensive list of all fonts installed in your system, a list of standard font sizes with an option to enter any other font size, and a copy of the picked colour list for choosing the font and background colours. The window can be resized to accommodate large fonts.

Colour List

If you don’t want to lose the picked colours when you exit Just Color Picker, or need to keep the colours separately for a future use, use the Save As menu item to save the colour list to a text file. Then use the Open menu item to load it back later. The Clear All command clears the list. You can also save the picked colours to an HTML file, which displays the picked colours in a more user-friendly format, but keep in mind that HTML files cannot be loaded back into the colour picker.

If you always work with the same colour list, you can make Just Color Picker open the same colour list file on every start: save your colour list to a file named “jcpicker.txt” to the directory where you placed jcpicker.exe file.

In addition, Just Color Picker can open, edit and save Photoshop’s .aco colour swatches (Adobe Color files) in RGB and HSB format. It can also read, edit and save GIMP’s .gpl palette files.

Portability and jcpicker.ini file (for Windows)

Just Colour Picker is a portable application, which means you don’t need to install or un-install it. Just double click on the jcpicker.exe file to start using it. If you want to remove Just Color Picker from your computer, simply delete the file.

When Just Colour Picker is run from the computer’s hard disk, it saves all its settings in the Just Color Picker.cfg file in the Application Data folder on disk C or in the Windows registry (for older versions). However, when Just Color Picker is run from a portable device, e.g. USB memory stick, it creates jcpicker.ini file and saves all its settings there. The jcpicker.ini file resides in the same folder where you keep jcpicker.exe and saves you from tuning Just Color Picker every time you run it on a new computer from a portable device.

Those who would prefer Just Colour Picker to create the .ini file even when it is run from the hard disk, and those who are particular about their Windows registry, should use “/ini” key when they run Just Color Picker for the first time. With this key, Just Color Picker will create the .ini file even when run from a non-portable device. And once there is a jcpicker.ini file in the same folder with jcpicker.exe, Just Color Picker will not use a config file or Windows registry and will keep all the settings in the .ini file. If you want to transfer Just Color Picker to another device or computer with all your settings, you should copy both jcpicker.exe and jcpicker.ini files.

How to use /ini key

You only need to use this key once, when you start Just Color Picker for the first time. Use command line or Run command from Start menu. Type the path to the jcpicker.exe file, then type space and /ini, and then press Enter. For example:

"C:\Portable Programs\ColourPicker\jcpicker.exe" /ini

Some information about the colour code formats

HTML, HEX and RGB colour codes consist of three parts that define the combination of Red, Green and Blue colour components. The first two characters of HTML and HEX code, or the first number of RGB code, define the red component, the next two characters or the second number define the green component, and the last two characters or the last number define the blue. The value of each part of the colour code can vary from 00 to FF for HTML and HEX, from 0 to 255 for RGB, and from 0 to 1 for RGB [0,1].

HSB/HSV. The HSB (Hue, Saturation, Brightness) or HSV (Hue, Saturation, Value) colour code defines a colour in terms of the following three components:

  • Hue (H) gives the colour its name, such as “pink” or “yellow”. Hue ranges from 0 to 360 degrees and looks like a colour wheel, starting with primary red at 0°, passing through green at 120° and blue at 240° and wrapping back to red at 360°; all mixtures between adjacent pairs of colours are linear.
  • Saturation (S) is the purity of the colour, how little the hue is diluted with white. The lower the saturation of a colour, the more faded or dull the colour looks. The higher the saturation, the purer and more intense the colour appears. Mixing pure colours with white produces so-called tints and reduces saturation. Saturation ranges from 0 to 100%.
  • Brightness (B)/Value (V) of a colour refers to the amount of black present in the hue. Mixing pure colours with black produces shades and, while leaving the saturation unchanged, affects the brightness/value of the colours. Value ranges from 0 to 100%, with pure colours at 100%, and near-black colours close to 0%.

Some applications use different ranges of the components. For example, S and V/B can vary from 0 to 1, H may be normalized to 0–100%, or all three components can vary from 0 to 255. Just Color Picker uses the “degree, percent, percent” notation.

HSL — the Hue, Saturation, Lightness code — has hue (H) defined as in HSB/HSV and ranging from 0 to 360°. In HSL tints and shades have full saturation (S), and only tones — mixtures with both black and white — have saturation less than 100%. Pure colours have lightness (L) 50%. Both saturation and lightness range from 0 to 100%. In addition to the standard HSL (0–360°, 0–100%, 0–100%) Just Color Picker has two other HSL formats with all thee parameters ranging from 0 to 255 in HSL(255) and from 0 to 240 in HSL(240).

If you require a parameter in 0–1.0 range while Just Color Picker shows it in the 0–100% range, you can easily convert one to another: e.g. 73% = 0.73.

CMYK is a color model used in color printing, refers to the four inks used in color printing — Cyan, Magenta, Yellow and Key (black); with each value ranging from 0 to 100. Because both RGB and CMYK colour cpaces are device-dependent, there is no perfect general conversion formula between them. Just Colour Picker uses the simplest conversion, good enough for most designs.

Using keyboard for greater mouse pointer precision (for Windows)

There are two way to move mouse cursor using the keyboard:

  • The simple way: make sure Just Color Picker window is active and press Ctrl + ArrowKeys.

  • The global way: Windows offers the Mouse Keys option for controlling mouse cursor with keyboard. To be able to move the mouse pointer with keys on your keyboard, you need to switch the feature on:

    In Windows XP: Start button – Settings – Control Panel – Accessibility Options – Mouse tab – Check “Use MouseKeys”.

    In Windows 7: open Ease of Access Center by clicking the Start button, then Control Panel, then Ease of Access, and then clicking Ease of Access Center. Click “Make the mouse easier to use”. Now, under “Control the mouse with the keyboard”, select the “Turn on Mouse Keys” check box.

    In Windows 8: go to Control Panel – All Control Panel Items – Ease of Access Center – Make the mouse easier to use. Check the “Turn on Mouse Keys” box.

    Now you should be able to use the numeric keypad on your keyboard to move the mouse pointer as follows:

    • 1 – down and to the left
    • 2 – down
    • 3 – down and to the right
    • 4 – left
    • 6 – right
    • 7 – up and to the left
    • 8 – up
    • 9 – up and to the right

    This function is a part of Windows and Just Color Picker has no control over it. Enabling this option will affect the whole system, not only Just Color Picker.

The standard boring disclaimer

Frequently Asked Questions

1. I press the default hotkey combination (Alt+X), but the Color Picker doesn’t pick the colour.

Sometimes the hotkey combination may be already assigned to another application installed on your computer. To fix the problem, simply choose a different hotkey combination in the Color Picker’s Options menu.

2. Why does Color Picker sometimes show slightly different colour codes for exactly same colour?

Occasionally, the colour code you set in the colour editor may be slightly different the code for the same colour displayed in the current colour area. This happens as a result of the rounding discrepancy that arises from calculations during colour format conversions. The difference is usually no greater that 1 gradation and should not be significant enough to become obvious to the human eye. For the same reason you may see a small difference in codes in different software.

3. When I run Just Color Picker from my USB stick, it creates jcpicker.ini file. What is it?

Just Color Picker recognises when it is run from a portable device and creates jcpicker.ini file that contains all its settings. It saves you tuning of Just Color Picker every time you run it on a new computer from a portable device. When you run Just Color Picker from your computer’s disk, it does not create the settings file, because all the settings are saved on that computer in this case. Read more about Just Color Picker’s ini file and portability.

4. How to uninstall Just Color Picker? I can’t find it in the list of installed programs in Windows.

Just Color Picker is a portable software and, therefore doesn’t need to be installed or uninstalled. To start using Just Color Picker, simply download the jcpicker.exe file and run it: nothing is being installed, and this is why Just Color Picker doesn’t appear in the list of installed software. To delete Just Color Picker from your computer, just delete the jcpicker.exe file.

More thorough users may also like to delete HKEY_CURRENT_USER\Software\AnnyStudio\ColorPicker registry key, if they didn’t run Just Color Picker from a portable device or didn’t use /ini key.

5. Can Just Color Picker be used in a commercial environment (for example, in a professional design studio)?

Yes. You can use Just Color Picker wherever you like. The only condition is that the program should not be modified or used in malicious activities.
