Forrest,
We have an employee with this issue and the trick for him is
distinguishing between certain shades of green and blue. With some wire
and lighting conditions, he will send me a cell phone pic of the wire
and ask if the green is on the right or the left. As long as you
don't go with both green and blue, I think he'd be in good shape anyway.

I know I can see WB APC cards' LEDs just fine in bright daylight, but
that's almost always in a NEMA box. In this same box I can easily see
the MT lights that you can't see easily in the truck.

True, it's not nearly as big of a problem as on a radio, but if
it's in a NEMA box on top of a grain leg or something like that,
it can still be a problem.

I don't know anything about colorblindness, but one
mistake I've seen on certain other products is using LEDs
that are barely visible in daylight... so that's another
thing to keep in mind.

A quick question for those who have problems
distinguishing colors.... or those who know about
colorblindness.
Let's assume I need to add a set of indicators to some
new products. I'm considering using some
multicolored leds (aka dual, tri, full) for indication
on a single led. For instance red might mean one
voltage and green another. Knowing what I know about
colorblindness (think high school biology - like 30
years ago), I realize that this would be a very bad
thing to do - or at least would be useless for some of
my customers.
What I don't understand is if there are color pairs
which are 'safe'. I.E. red/yellow vs red/green. Or
Blue/Amber, etc.....
So, now is the chance for all of you who can't
distinguish led colors to let me know what stupid
things *not* to do. Or perhaps suggest what the best
options are.
