Colors are fine.
There's a lot of color ways coming out and it seems like right now, considering the state of the hobby, sets need something seriously unique to build interest. GMK Nerve has a crazy pop of color with some really interesting novelties, GMK ZX is harkening back to the Sinclair and incorporates R0 and R5 keycaps, GMK FTRO has some beautiful marketing and renders with some unique sub-legends.
Try giving the community something to talk about, to build interest, so feedback comes naturally.
GLWIC!
