COLORLESS
Black and White are colorless. Even though white has ALL THE COLORS in it, its not a color. Strange.
Colorless is also everything. For a blind person. Perhaps they see colors, when high? Who knows. Probably them.
I am colorless sometimes. When I stand in the dark. Watching people through glass. Is glass colorless? I cant see color in them. I only see the people.
What color do YOU like the least? Why? I like the blue of some hearts. Hints can be colorful, even though the letters are colorless.
