Neon Rainbow Galaxy Tutorial

Hello friends! I’m sharing a colorful Rainbow Galaxy idea to paint in your sketchbook today. In this tutorial, you will learn how to create a rainbow galaxy in just a few easy steps. Paint this in your sketchbook or even on canvas!

You all know I love writing down quotes and today I’m a painting galaxy to go with my quote! This post was created in partnership with DecoArt. I love their products and sharing creative ways to use them with you all.

Step by Step Tutorial:

Let’s get started! I’m using a stipple paintbrush today and a dot journal as my sketchbook. The Dot journal I have has really thick pages and can tolerate acrylic paints without warping. Use a good mixed media sketchbook otherwise.

The paints I have are NEW! They are the DecoArt Black Light Neons, now available at Michaels.

Start by adding a layer of black around the corner areas. Blend that into the paint using a circular motion.

Next, add your colors! I used all of the rainbow colors and just added dots of colors onto the page, to begin with. Quickly blend the colors on the page itself with a circular motion.

The first coat of color will not cover the paper opaquely, as we used just a little paint. Add more color onto each section and blend.

Smooth our all the paintbrush strokes with a soft paintbrush and a little bit of white paint. I love how the circular motion mimics the look of a clouds or a galaxy already.

Final step is to add a nice dusting of stars! For this I used an old tooth brush and dipped it in white acrylic paint (that has been thinned down with water) Spray tiny white dots all over the page with this.

All Done!

Here is how my Rainbow galaxy page turned out! I loved the experience of painting it!

The fun part of these paints is that they GLOW! Shine a black UV light on your page in the dark and the colors come alive! SO MUCH FUN!

I tried adding more stars, bigger shining stars to the background, but honestly- I was a bit scared I would spoil it at this stage. So I did what I do well- I lettered a quote onto it with white acrylic paint 🙂
