Being the husband of a blind wife, I have a unique perspective on this particular question. She hasn’t always been blind so she understands colors, but I still have to describe a lot of different things to her that she can’t see. I try not come up with weird descriptions of things just to mess with her…often. I can’t help it though, sometimes that crashing sound just might be monkeys fighting over a pink flamingo lawn ornament with sausage link nunchucks. Don’t judge me. You weren’t there. It could have been. I think the thing she hates the most is that I am a very quiet person, and at times I just sort of suddenly appear in front of her. Scares the goobers out of her.
Describing colors is easy when you only worry about the main three, the rest don’t even matter, their just a mixture of the three anyway.

Well I would imagine the color Black could be understood as well since that’s what they see all the time.
(and as far as the monkeys fighting, I totally get that, it happens to me too and I CAN see…hmm..maybe I should get my eyes checked.)
Fighting ninja monkeys are the scourge of the sausage link field. But they are entertaining.
