That's the impression I get, but this hottipped paragraph in Tastes Like Purple
Doesn't cover characters just speaking metaphorically.* A key difference between this trope and Tastes Like Feet is that normally it would be impossible for people to taste or hear colors, but it is quite possible for people to taste things like feet and motor oil. The exception of course is those with the condition synesthesia. And most of the color examples at Tastes Like Feet are metaphors: a food with color X is described as tasting like color X. Those don't belong here. Only include examples where a character is made to taste (or hear or see, but taste is most common) something which rightfully does not have a taste at all.
(bolded for emphasis)
Explicitly disallows quite a few examples from Tastes Like Feet
that don't belong on that page either. Assuming, of course, we want to consider those examples of either at all.
They lost me. Forgot me. Made you from parts of me. If you're the One, my father's son, what am I supposed to be?
