Color Me Happy!

If I were the color blue,
I'd sing sad songs for you.

If I were the color yellow,
I'd be a happy fellow.

If I were the color red
I'd look like me when I bled.

If I were the color green,
I'd grow like a big string bean.

If I were the color brown,
I'd be a chocolate town.

If I were the color pink,
I'd be a lemony drink.

If I were the color purple,
Nothing would rhyme with me.
