In the op you did in fact deny the entitlement
“because it doesn’t even make sense. Colors are just various forms of light. Why should it be expected that one in particular appeal to you more than any others?
and “what’s your favorite food?”. That one is the opposite of chinuch. It’s in effect stating that food is to be eaten for purposes other than nourishment.”
Never mind the fact that halacha takes favorite foods into account eg regarding kedicma for brachos and doesnt dismiss it as “the opposite in chinuch”
Asking these questions is actually GOOD chinuch since at the age when most of these questions are asked these are things that children care about, and parents/others showing interest in things important to their children is excellent chinuch.
