Color Blindness and HP Prime keys color choice

[Han]

What about just changing the keys to be black with white, bright orange, and bright blue (or cyan) for the lettering (much like the colors of the keys near the arrow-pad). Isn't white plastic more expensive to make, anyway? (Not sure where I read that, but vaguely recalling some Apple-related article on how expensive white plastic can be, relatively speaking)

I personally like the aluminum overlay :-)
