[Elecraft] K-2 Blue Display

[Ron D'Eau Claire]

Yes, the "blue" of sunlight is comparative. Those who work with photography
(or videography) thinks of it as blue because that's what it is compared to
incandescent - even the big halogen incandescents we used to use in studios
- just like fluorescents were bright green. 

It's amazing how our brains adapt so well, establishing a "white reference"
to the dominant illumination making it tough to see what havoc that light
might be playing on our color vision. 

I have a hard time seeing the red on gray on the buttons too, and my color
vision is considered entirely "normal" - so don't feel too bad. There just
isn't enough contrast to make it easy without pouring a lot of light on the
panel. Like you, I've pretty well memorized the red legends.

I have monochrome vision and a decreased sensitivity at short 
wavelengths [poor choice of parents and grandparents :-) ]  Most blues 
are indistinguishable from black for me.  I'm pretty happy with my K3 
display which is highly readable.  I have a hard time seeing the numeric 
legends on the key pad, my wife tells me they are dark red on a dark 
gray key, but I've figured out the keypad by position just fine.

OTOH, my total cholesterol is 105, the "good" is high, the "bad" is low, 
the result of very good choice of parents.  Life is sort of a crap 
shoot, and I'll stick with the stock K3 display.
