"Red-green color blindness is the most common... they generally have difficulty distinguishing between reds, greens, browns and oranges."
that’s the same spectrum example i had based my previous post on; they can not be distinguished between each other chromaticly, but their apparent brightness differs? so you could not tell them apart individually, but if you saw them next to each there would be some bit of difference? still stands to indicate a need for a self check.
if that’s a misunderstanding on my part, then your prior post stands, and i retract my statement.
