What about foreign words and numbers? Do they remain black and white until you tell the person what the words and numbers stand for?

I'm not sure. A lot of languages use arabic numbers. Perhaps it's the shape that gives them a color? As for foreign words, perhaps it's the combination of letters that give off a certain hue. I don't remember reading about those instances. It would be interesting to read about that.
