Also, thoughts on new colors in OP?
Still not a fan of the low contrast mods(especially on the lighter set), also liked the yellow alphas.
Also, is it just me or does the "red" look orange-ish? I'd maybe prefer a deeper red to increase contrast.
Imho the main colors are yellow, purple and white/very light blue, with the red as a accent color that would work in a few combos, just no red text on purple keys please. If it REALLY has to stay Red Text on all keys, one of the few red/purple combos that offer a nice contrast would be scarlet red/indigo, maybe try that for a mockup.
I'll play around with color combos later today, still got other stuff to do first.
