Sorry, but it will be CMY legends on black keycaps next no RGB.
Since this one is likely to die, I will be starting new in the next weeks. I know I previously said anything that is above MOQ will go... but I don't want to do spacebar only now and then offer spacebar again next time (specific colors black, cyan, magenta, yellow) so... if nothing else makes it like the MODs pack then this whole thing will be cancelled.
