[Elecraft] K3 Colour Contrast

[Alan Bloom]

The issue is not aesthetics, but rather utility.  Something like 9% of
American males are red-green color blind (by far the most common type of
color blindness).  There are certain colors, and certain combinations of
colors, that are very difficult for them to discern.  It makes sense for
manufacturers to choose colors that can be seen easily both by people
with normal color vision and those of us with some degree of red-green
color blindness.

The many of us (mostly males) who have reduced red sensitivity will have found the numerals on the dark grey keypad very hard to read.  But at least we can congratulate Elecraft on avoiding the even greater menace of those pesky multi-coloured LEDs!
