If you don't have a rainbow to give.
Give a smile. It works just the same.

I'm collecting for God. Can you spare a smile?

Liking colors doesn't make you shallow.
It gives you depth!

Love is spelt C-O-L-O-R.
And
Color is spelt L-O-V-E.

When you get to the end of the rainbow, you haven't even started yet.

A friend of mine gave me a rainbow and it made me happy. So, I in turn, gave it to a complete stranger and then it made both of us smile.
