Heart Shaped Watercolor Resist Art Tips

When children use watercolors to paint an area that was colored with white crayon or oil pastel they are surprised to see the drawings appear, even when they know the art is there. It’s magic… Invite the kids to experiment and have fun!

We like to use white oil pastels best because we like the way they work as a watercolor resist medium. Create an experiment with watercolor resist mediums to learn which resist medium you like best.

Working with colored crayons and pastels creates colorful designs that the child will be able to see before they paint with watercolors. Drawing only with white makes the designs hard to see before the child paints.

Pop over to have a look at Easter Egg Surprise Art if you would like to see how colored crayons and pastels look after they have been painted over with watercolors.

Ask children to choose 2 – 3 watercolors to paint heart art if you would like to encourage color-mixing and experimenting. You are welcome to use more colors if desired.

Offer only the primary colors (red, yellow, and blue) if you want color-mixing to be a part of your watercolor surprise heart art lesson. Learn more about working with watercolors in wet-on-wet watercolor painting.

How to Make a Watercolor Surprise Heart Art with the Wet-on-Wet Watercolor Technique

The second way to create watercolor surprise heart art is to use the wet-on-wet watercolor technique. For best results, use only two primary colors for each heart and watch the surprise color appear!

The surprise is revealed when the child discovers the magical third color. Painting with watercolors in this way allows children to experience color mixing so they can learn first hand that blue and yellow make green, or red and yellow make orange or red and blue make purple.

Primary Color-Mixing Heart Painting Idea

You could also call this heart watercolor painting idea primary color mixing heart art, but I think “surprise” is more fun for the little ones.

Besides, who would want to spoil the surprise by telling children that they will be doing color mixing?!

Shhh… it’ll be our little secret. 😉

Just look at how beautifully the primary colors (red, yellow and blue) blended below to create the secondary colors (orange, green and purple) in the heart art watercolor painting below.

My daughter has been working on wet-on-wet watercolor paintings using all three primary colors for a few years so she has already been surprised by the secret of the secondary colors appearing.

To make her heart art project into more of a surprise, I decided to use a chunk of white pastel to draw hearts on the inside of the heart shaped template. She loved it!

Surprise Wet-on-wet Watercolor Heart Painting Step-by-Step Directions

Another option is to use a spray bottle filled with water to get the paper wet and then wait a few minutes to paint.

NOTE: The template ink runs a tiny bit when you spray it, but it is possible to cut the heart out when it’s dry for a cleaner look like the hearts pictured throughout this article. Another option is to cut the heart out before spraying it with water.
