Do people base their likes/dislikes in food on taste, as they claim, or on color?

Take the classic m & m. People have told me that a particular color, let’s say red, tastes better than the other colors. Is there involuntary visual assessment going on here?

This might be a weird question, I can’t tell. Let me know if it is.

Also, what do you think is the most important aspect of a food when judging it to be good or bad? (Let’s say you don’t know what it’s made of) Texture? Taste? Color? Overall look? Smell?
