What if?

Imagine if the world had no colour, if everything was just a dull grey. How could we live without no colour, lips grey, hearts black. How could there be art with no colour? How could we smile, sing, be happy without no colour?  I often think about what it would be like if i was colour blind...
What would you do if all you saw was black and white? How would you know if a person was a red head, brunette, or black headed? If your eyes were, blue, brown, green or hazel? I don't know what i would do if i could see no colour...
If i couldn't see a rainbow, or if i couldn't see sunsets or sunrise... I think i would cry.
I can't imagine a world without colour,
Can you?
