Colorblind Assistant is free software that instantly picks the color from the mouse pointer, providing you with a written name of the color, as well as other useful data such as RGB values and bar graphs, brightness and saturation.
The app has a zoom pane for fine pixel detection, and sits nicely in your desktop tray when not in use. Colorblind Assistant runs in a small window that you can easily use alongside graphics programs, applications, games, video-editing software and movie players. The pixel data updates in real-time, so use with animations and movies is just as easy as still images.
Colorblind Assistant is compatible with all Windows Operating Systems, but is recommend for use with Windows XP, Windows Vista, Windows 7 or Windows 8.
