HTML Colour Toy is KateGlover.co.uk‘s free application coming in handy for those working with html or any other application that requires HEX codes for colors.

The application is simple and works well even on high resolutions like WVGA: you mix the color of your choice with the aid of the three (Red, Green, Blue) sliders, resulting color will be displayed in the top box and its HEX number will be shown just below it.
