Us at Frozen Flame Studios LLC. have developed an app on Steam using C2 called "Swatcher". The idea behind the app is to allow you select and organize your color palettes for your projects by selecting them through RGB, HSV, the color wheel, CMYK, or HEX code. Every color you choose or save will give you the RGB, HSV, CMYK, and HEX code accordingly, as well.
We're currently running a 20% off new release discount - we figure this would be something to help aspiring (and professional) artists out there!
Hope you enjoy.
