100%. Same with stop lights - even if you can’t see certain colors well people can still tell that there is a difference, at least in hue (or in your case shininess!). As long as they associate correctly, like the red one, however perceived, as being stop, they can adapt.

I always thought it was cool that when we test color vision the first page (the 12 usually) is actually a decoy to be able to see if people are trying to fake the tester for some secondary gain. Even a color bind person (no matter which type) will be able to tell you the number based on contrast, not color. Fun fact.
