Sometimes white is a color. Sometimes it's not.
That helps, doesn't it!
To Akro, in the Tri-Color Agates, the three colors could include white. (On the left in the Tri Color line in this picture is a Lifesaver -- yellow, red, green -- the green may be hard for you to see in this particular scan. The rest have white as a color.) Similar with Prize Names. They're "two-color" ... and sometimes one of the colors is white.
Popeyes are a different category. They have clear and white and two other colors and we sort of don't count the white as a color there. I can't remember the other examples where we don't count white. They'll probably come to me.
