What color are you supposed to be, again?

I went to the grocery store yesterday to buy ingredients for onion soup. But when I got over to the onion display, all the onions were... white?

Onions aren't white, onions are yellow.

I'm standing there, terribly confused as to why these white things are labelled "oignons" when clearly they aren't, and then it hits me:

Oh, yeah. They sell white onions in the States, don't they? I used to buy them until my grandma broke me of the habit.

Sorry, onions. Didn't mean to judge you by the color of your skin.
