My Art, and a Black Rainbow?

This pix shows how a rainbow normally is thought of, it is a display of light and water droplets. Yesterday I gave my Granddaughters an art set for each of them. Well Miss K wanted to paint right away. We painted then Miss G got in the mix and soon Miss C was cutting paper as well.

Miss K started to paint a rainbow (Gods Promise) Purple, Blue, and .....Black????

Well Bob Ross said,"Its your world on your canvas so paint what you want."
So If you see a black stripe in your rainbow then put it in there! It is Important to at least paint something.

Well kids keep your rainbow up in the air and paint away!
