[IxDA Discuss] Amber and Yellow color perception

[pauric]

We use 'yellow' as a label on the front of our boxes (signifies reduced
functionality)  It is for all intents and purposes indistinguishable from
Amber.  I believe Amber is produced by combining a Green and Yellow/Red LED,
but I'm not 100% sure which, its been a while since we played with
combinations.

I do remember one case where a vendor produced Amber instead of Yellow on
some alpha hardware.  I think some loaded a component feeder with the wrong
part.  It simply looked odd to users, subtly different but not
distinguishable.  From my experience with LEDs I would strongly advise
against using yellow/amber to represnt different states.

But, I dont have and hard research.
