Is it normal if when ever I see a color, I get a taste in my mouth? - mouth to color

Since I can remember, whenever I have a color that I hit the taste in the mouth. The flavors are not really describe because it's not like anything I never actually eaten, but in general, cool colors more of a flavor and aroma Metally warm colors, such as wood or plants. I hate observe red-blue-purple, or green, because it is a painful way aftertaste in your mouth.
