How to paint a relaxing watercolor rainbow

Want to paint a fabulously fun rainbow using watercolors? Here is a simple, step by step guide for painting a cheerful rainbow using different brush strokes and patterns. This is a relaxing painting activity that you can do when you have a limited spot of time. 

Hi! I’m Stacey Dodd from The Pigeon Letters Design Team and I am an avid watercolor paint-maker and artist based in New Zealand. Here's what you'll need to follow along...

 

Supplies:

  •  Size 2, 6, and 8 round paint brush
  •  2 jars of water – 1 for rinsing dirty water and 1 for clean water
  •  Paper towel or rag
  •  3 matte watercolors – I used a blue, magenta and yellow
  •  2 shimmer watercolors – I used a bronze and silver
  • Washi tape
  • Cold press paper

Step 1: Practice Your Brush Strokes

Before we jump into painting a fabulous rainbow, let's first practice a few different brush stroke patterns. This will be a great way for you to get familiar with your paintbrush.

 

  

 

Step 2: Prepare and Secure the Paper 

You now need to cut your paper to a size suitable for you. I have cut mine to an A6 size. This is approximately 4-1/8 x 5-7/8 inches or 105 x 148 mm

Secure the paper to your surface using washi tape.

 

 

 

Step 3: Pre-wet Your Paints

Pre-wet your paints and allow them to soak for 1 – 2 minutes for optimal pigmentation. You can alternatively prepare your paint in a ceramic dish.

 

 

  

Step 4: Paint the First Layer

Using a bigger brush, start with a color (I used magenta here) for the larger rainbow arc. 

 

 

Do another thinner arc using another color (I used blue here) and follow this with a much thinner line (I used yellow here)

I then used a different  shimmer paint (the bronze) for a thicker line following that with a slightly thicker yellow line. The last arc is a filled in arc where I used silver.

 

 

 

Step 5: Paint the Last Layer

Ensure that your paint is dry. You can use a hairdryer or heat tool to speed this up or have a cuppa tea!

Once dry, choose a shimmer to add in a pattern. I used silver and added dashes to create a contrast between the two outer thicker arcs. 

 

 

I then used the other shimmer color (bronze) and added more pattern, little dots on top of the yellow, to break up the yellow and create a balance of shimmer and matte on the rainbow itself.

 

 

Hot Tip: Do not worry about perfecting the curves of the rainbow. If it is a little wonky, this gives it character! 

I hope you enjoyed painting cheerful rainbows with me today! I would love to see your rainbows so please tag Peggy (@thepigeonletters) and me (@stakiwicolours) so that I can share or see them.
