Betcha didn't know these were part of the rainbow

I overheard Addi and her friend Salina talking while they were coloring today.

Addi: I'm using blue because blue is my daddy's favorite color.
Salina: My favorite colors are purple and hot pink.
Addi: I like cold pink, purple and hot blue.
Salina: Really, I like all the colors of the rainbow.
Addi: Me, too. But not brown.
Salina: I like brown.
Addi: I only like hot brown.
