JIMWICh: Yes, yes, yes. My color vision isn’t as bad as yours (00FF00 and FFFF00 look different to me) but I fully agree with your description. Any color with a strong component is fine but weak ones just aren’t there. The darker the base color the more of a factor this is.
A couple more effects I’ve noticed and I’ll throw out there:
-
The smaller the sample of color the harder it is for me to deal with.
-
With a reference key I can decode colors that I can’t decode otherwise. I can read (although I have long since forgotten them) resistor color codes with a card next to the resistor. Merely having the card elsewhere in my vision isn’t enough. A card won’t let me read capacitor codes, though. (Resistor codes are bands. Capacitor codes are dots.)
