Wanna bet? I can't eat ice cream but I tolerate frozen yogurt just fine. They are made differently and there is quite a bit of difference in the taste.
Now as to car colors, I agree. There is s great scene in Mr. Blandings Builds His Dream House where Myrna Loy spends a good 5 minutes describing to the contractor what colors she wants, it is quite funny. The kitchen is to be yellow, not too bright like the sun, and not too pale; have the painter buy a pound of butter and match that. She hands the contractor a spool of thread and tells him to match that. She leaves and the contractor asks the painter if he got all that. The painter says "Yea, white, blue, yellow, red & green."
