Color Oracle takes the guesswork out of designing for color blindness by showing you in real time what people with common color vision deficiencies will see. Color Oracle applies a full screen color filter to art you are designing - independently of the software that you are using.
Seeing is believing! Instantaneously identify and correct problem colors in your art using Color Oracle's system-wide menu and keyboard shortcuts accessible in any program.
Works great. Thanks for making this free!
I hope I'm not missing any hidden (or even obvious) feature now, but here's a feature request:
It would be nice if you could keep it active all the time, until you press some key combination. That way, you can design without having to stop and check results in Color Oracle.
