Besides, AFAIK the only way to achieve that would be to totally replace all the shots where Kirk steps outside his assigned color with CGI. That means computer-generated backgrounds, actors, everything.
Wouldn't the sensible approach be to redraw just the floor? That is, apply a new, nicely uniform and simple floor color to those bits where Kirk's foot inconveniently falls, but only in those shots where it happens, so that the floor pattern in theory ends up looking different in different shots but nobody really notices.
Heck, if the exact texture turned out too difficult to reproduce faithfully, just choose an all-new, scientifictionally uniform and bright color... Thus better matching the brains!
