[Elecraft] Blue Displays and Visual Acuity

[Steve Ellington]

For long periods of exposure, like the front panel of a radio, it seems like 
one would prefer a color that is easy on the eyes and not glaring. Green and 
orange are bit tiring while soft blue is soothing. Next, we need plenty of 
contrast so we can see the numbers. Here's where we have trouble. TenTec is 
using blue on the Jupier now. It's soothing but the white numbers make the 
display look milky. Black seems too close to blue and doesn't show up well. 
The orange display on the K3 is a bit tiring but I can read it from across 
the room. My favorites are displays with a black background and bright 
colored numbers. Even white looks good.
