Not simultaneously. One or the other, and I think it depends on context, especially if one comes after the other. Together with 3, 7 is almost always orange, but alone it can be yellow. 3 is orange on its own sometimes.

And orange here is more like butterscotch the flavor than it is the color. Gah, no wonder I trained myself out of it.

I envy those who have a 1-to-1 mapping of sensation to concept. For me it is just a big ol' inchoate mélange.

Do you enjoy it?
