In the recent Netflix Daredevil series, when receiving his first official armor at the end of the first season, Matt is told that "the red parts" offer one kind of protection, while "the black parts" offer another.
Now, obviously the armorer didn't know that Daredevil was blind, and to be fair, Daredevil isn't hampered too much by being blind anyway, in a practical sense. He can do pretty much anything that a normal person can do, thanks to his heightened other senses. And with regard to the armor specifically, he could probably figure out the relative protection capabilities by touch, or by testing its material and flexibility while wearing it, etc.
But the question remains: does Daredevil have any mechanism for distinguishing an object based on its color?
