I am monochromatic [pretty rare unless you're from a remote island in 
the S. Pacific I can't remember the name of -- I'm not from there and 
I'm pretty sure none of my ancestors are either].  I can't see the 
numerals on my K3 keypad which my wife tells me are red on a dark gray 
button.  I can discern all the rest of the legends.  I've figured out 
where the keypad keys are however so I'm not going to file an ADA suit 
against Elecraft :-)  I do have much better vision in very dim light 
than all the rest of you.

Please don't ask me, "What colors can you see?"  I can see all of them. 
I just can't name them, and lots of them all look alike to me.  I began 
to realize I wasn't discerning colors well when everyone had a lot of 
names for colors that looked the same to me.  I realized I was 
monochromatic when color TV appeared and it looked just like B&W.  I've 
run across some pretty difficult web sites.  Windoze Default color 
scheme works OK for me.
