Rainbow Acrylic Painting

I discovered how to make this while I was trying to make something else! This project ONLY works with watercolor paper. It is very easy to make. I hope you enjoy this!
Supplies

For this project you will need white watercolor paper, acrylic paint, And a paintbrush or sponge.
Starting the Project

First you will squirt little blobs of acrylic paint onto your paper
Using the Sponge

Next you use our sponge or paintbrush to mix the colors together. It will turn into a color like the photo. You will know it worked if you can see rainbow under it
Washing It Off

Wash off your paper so the brown is gone. Then let it dry.
Finished!
You have finished the project! I hope you enjoyed making it!
