Color blindness is X-linked and supposedly 16 times as prevalent in males as females. Yet I find just as many women who can’t tell the difference between green and yellow LEDs as men.

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. -- Forrest Christian CEO, PacketFlux Technologies, Inc.
