Which platform supported by Electron does not have existing color picker applications?

Been using GColor2 forever on Linux. And I believe there are others.

Don't really see how this improves it. I use Mac OS as well but I don't miss the color picker from Mac OS when I'm using Linux, not sure what his problem is. Or the attitude in general, I wouldn't want to be running something showing at all times such a cute name on screen. No thanks.
