I’m interested in the F77 with Ultra compact case. I would prefer a black case but the problem is that, taking a look at the very few photos available, it seems that the keycaps are the same color as the old-fashoned keyboards. That kind of light beige color goes well with old computer and old keyboard cases, but not much with a modern black case. Will they be available in a more neutral gray or white color? Also, will all keycaps be available in any of the two colors (usually darker for the modifiers and bright for the alphas)?
I had great success dying Unicomp keycaps. (There are numerous guides out there — how to use fabric dye.) I am typing now on orange Unicomp keycaps that were originally pearl. I plan on buying another set of white and dying those for the new Model F77.
Unicomp also sells grey keys, they are a much better match with black than pearl/pebble in my opinion, you should consider to deliver grey keys too.
