Please note that the pictures are just for reference, actual PBT color availability is limited and the final color won't 100% match!
1) Cold gray
Ala SGI Granite or WYSE.
good: goes well with anything
bad: boring

2) Warm gray
Like your slightly yellowed old abs keyboard
good: it's retro...
bad: ... no it's just old.

3) Real beige
Like Model M
good: c'mon it's model m
bad: not the best combo with black cases

4) Charcoal
This is something completely different and I don't think there's a keyboard available in PBT with this color. Think of it as a Dolch with black legends. The contrast is not high, but the end result might be nice and original.
good: original and classy
bad: low legend contrast

note that ALL LEGENDS will be black!
