Whether you’re curious, looking to understand pigments better, or simply want natural contents, we’ll show you how to make watercolor paint at home. The added bonus? It’s great fun for the kids.

Though more time-consuming than going to a shop, making your own watercolor paint is a great way to explore how different pigments work. Once you’ve learned the theory, you will be able to control the hue, value, and intensity of each color to create specific shades you may not be able to find using commercial paint sets.

You can’t always be sure exactly what is used in mass-produced watercolor paints. By making natural watercolor paint yourself, you can ensure quality, achieve better luminosity, and do away with fillers, chemical preservatives, heavy metals, petroleum-based pigments, and toxins. You can also choose a reusable pallette, such as one made of glass, to avoid plastic waste from store-bought paint sets.

Watercolor paint is comprised of a pigment suspended in a binder made of gum arabic, water, and other additives to preserve and stabilize the paint. Because each watercolor manufacturer differs slightly in their methods, ingredients, or tools used, the characteristics of the paint vary from brand to brand. The same goes for artists who make their own paint, as they fine-tune their recipes over time.

The ingredients for homemade watercolors generally include:

Dry pigment

Choose your preferred pigment. Natural earth/mineral pigments, made from rocks and clay, are thought to be less toxic than pigments like cadmium or cobalt. However, it’s always important to protect your hands by wearing latex gloves and avoid breathing in the dust by using a face mask over your mouth and nose. Natural pigments come in a variety of colors – look for them at your local craft store. You can also purchase them through Natural Earth Paint, who give detailed information on their sources and methods.

Gum arabic

Extracted from the acacia tree, gum arabic is a water soluble gum that acts as the “glue” that binds the pigment. If you can’t find it pre-ground as powder, you can grind it yourself with a mortar and pestle. 


Used often in skincare products, glycerin is a humectant and a plasticiser which can be bought at a pharmacy. It is used to prevent watercolors from cracking and crumbling when dry.

Optional preservatives:

Clove oil/ thyme oil

These oils act as natural antibacterial and antifungal agents that can prevent the paint from growing mold.
