Colorblind?

Colors have been a hard concept for you to grasp. Red is green, blue is purple, everything else is yellow. At first, I wasn't too concerned, but then I started to worry because you were understanding letters and numbers, so why not colors?! I was starting to think that maybe you were colorblind! However, you proved me wrong this night when you accurately put all of the colored fishies in their appropriate places on your fish puzzle!
