Awkwardness at the deli counter...

I was at the grocery store the other day getting some cheese from the deli. I ordered some American cheese and the lady behind the counter asked me if I would like white or yellow. I never really thought of it before, but I was feeling particularly contemplative that day. Does anyone else feel a little racist when ordering American cheese at the deli counter and given the yellow or white option? I, for one, don't see any difference between yellow and white American cheese. I will have to Google the difference some day when I have time. So, when I go to the counter and say "I would like some white American," in my mind I may as well be saying "I reject your American cheese of color! Give me the pure Arian cheese!" Maybe I am overthinking it?
