Watercolor Rainbow Process Art

There are always themes we do for spring and that is rainbows! I think the one sign of spring for me has always been rainbows.

I love to look for them everywhere! This past summer we saw a wonderful double rainbow while we drove cross country. It was amazing to see how wonderful they look in the sky.

We always have fun reading books with our art projects. Yup ever now that they are old we still pick a book. It might be that we all take turns reading now. It makes the art time loads of fun.

One book we love is the There Was an Old Lady Who Swallowed a Clover and the rainbow at the end of the book. These books are a favorite of ours.

How we did the panting

First, we drew the rainbows in pencil. This made sure we had our colors and where we wanted to put them on the page. Plus you can always redraw your lines with a pencil first.

Next, we colored each of the lines with one color from the rainbow. We used oil pastels for the colors. This helped the colors not to blend into each other as much. Plus helped us keep trace of what color we were painting. For the red we did two red lines for the top.

We started in on the watercolor painting. We did this similar to how we did our heart painting. We filled the whole arch of the rainbow with water first. We always keep one brush and bowl just with water for these paintings

Then we start painting. Each time we do this we get loads of paint on the brush and dip it into the water. The effects as it spreads are really neat to see. One drop of color spreads really fast through the water. This is fun to see how to works. There are many wants to do this painting and makes each painting unique to the person who made it.

If your paper curls up some and it might put something on it to hold it flat. We used some pet counters we had close by. You can use just about anything.
