I don't know if it'd be practical, but what would be incredible is if you could do a RGB set but with all grey or blue keycaps, but have the *text* be RGB... If that's doable let me know because I think I would need to buy a set of caps then. I swear I saw a set of keycaps - I think mixed blue/grey - like that once, but I'll be damned if I can find a pic to illustrate.
