More Quirks

What's all this past-tense nonsense? Blue and gray still get conflated, as do red and orange. Just watch an old western, where they used blue filters for "night" scenes to emulate the graying-out of low-light conditions without losing the ability for the viewer to see what was going on, or look at the hair of a natural redhead - or the fur of a red fox - where the "red" in question is quite clearly some flavor of orange. I'm fairly confident there are also some animals that are called "blue" when they have gray fur/feathers - the bluetick coonhound comes to mind.
