A Once Unnoticed Color

Once there was a color
But I didn't see it there
Once I saw a color
But I didn't know or care
Once people were different
But I didn't know to stare
Once there was a color
But I didn't see it there
It's funny how we learn things
As each day we learn and grow
It's funny how we learn things
That we didn't want to know

A/N: There was one, but now there isn't. So there.
