Making your own natural paints is a rewarding and sustainable way to create art while minimizing environmental impact. Store-bought paints often contain synthetic pigments, petroleum-based binders, and other chemicals that can be harmful to both artists and the planet. By using natural materials, you can create beautiful, vibrant colors straight from nature, reducing waste and ensuring that your art practice aligns with sustainable values. In this guide, I’ll walk you through everything you need to know to start making your own natural paints.

Why Choose Natural Paints?

Before diving into the process, let’s explore why natural paints are worth considering:

1. Eco-Friendly – Natural paints are biodegradable and don’t contribute to pollution.
2. Non-Toxic – Many store-bought paints contain heavy metals and volatile organic compounds (VOCs), which can be harmful when inhaled.
3. Cost-Effective – Many natural pigments can be sourced from your kitchen, garden, or local environment for free.
4. Uniquely Beautiful – Natural pigments create a rich, organic aesthetic that synthetic colors often lack.
5. Connection to Nature – Gathering and preparing your own materials fosters a deeper appreciation for the natural world.

Sourcing Natural Pigments

Natural pigments come from a variety of sources, including plants, minerals, and even insects. Here are some common sources of color:

• Reds & Pinks – Beetroot, madder root, hibiscus, avocado pits
• Yellows & Oranges – Turmeric, onion skins, saffron, dandelion flowers
• Blues & Purples – Red cabbage, blueberries, elderberries
• Greens – Spinach, nettles, wheatgrass
• Browns & Blacks – Coffee grounds, walnut husks, charcoal
• Whites – Chalk, eggshells, kaolin clay

Extracting Pigments

To use these natural materials for paint, you’ll need to extract the pigments. The process varies depending on the material:

Grinding Minerals and Earth Pigments

For clay, charcoal, and other mineral-based pigments:

1. Crush your material using a mortar and pestle or hammer.
2. Sift the powder through a fine mesh to remove large particles.
3. Mix with water to create a smooth paste.

Safety Tip: Be sure to wear a mask any time you are dealing with powdered pigments. Although natural pigments are generally less toxic than synthetic ones, inhaling fine particles can still be harmful. Even non-toxic materials like clay, chalk, and plant-based powders can irritate the respiratory system and accumulate in the lungs over time, potentially causing respiratory issues. Always work in a well-ventilated area and wear a dust mask when handling dry pigments.

Boiling Plant-Based Pigments

For fruits, flowers, and vegetables:

1. Chop the material into small pieces.
2. Simmer in water for 30-60 minutes.
3. Strain out solids and reduce the liquid to intensify the color.

How to turn boiled pigments into powder:

1. Strain & Dry – After boiling plant materials, strain out the solids and spread the remaining pigment-rich paste on a glass or non-porous surface. Let it air-dry completely in a well-ventilated area or use a dehydrator at a low temperature.
2. Break Up the Residue – Once fully dried, scrape the pigment residue into smaller chunks.
3. Grind into Powder – Use a mortar and pestle, spice grinder, or fine sieve to crush the dried pigment into a fine powder.
4. Store Properly – Keep the powdered pigment in airtight containers, away from moisture and light to preserve its color.

Alcohol or Vinegar Extraction

For stubborn plant pigments (like chlorophyll):

1. Soak leaves or petals in isopropyl alcohol or vinegar for several hours.
2. Strain and use the liquid as pigment.

Making the Paint

Once you have your pigments, it’s time to turn them into paint by adding a binder. The binder helps the pigment adhere to a surface and improves longevity. Different types of paints require different binders.

Watercolors

Ingredients:

• 1 tsp natural pigment
• 1 tsp gum arabic (natural tree resin)
• A few drops of honey (for smoothness)
• Water as needed

Instructions:

1. Mix the pigment with a small amount of water to form a paste.
2. Add gum arabic and honey, stirring until smooth.
3. Store in small containers or let dry in a palette to rehydrate when needed.

Acrylic-Like Paints

Ingredients:

• 1 tsp natural pigment
• 1 tsp egg yolk or plant-based oil (such as linseed or walnut oil)
• A few drops of water

Instructions:

1. Blend the pigment with the egg yolk or oil.
2. Add a few drops of water for desired consistency.
3. Use immediately, as egg-based paints spoil quickly.

Oil Paints

Ingredients:

• 1 tsp natural pigment
• 1 tsp linseed or walnut oil
• A glass palette and muller (for mixing)

Instructions:

1. Place pigment on a glass surface.
2. Add a small amount of oil and use a muller to blend until smooth.
3. Store in an airtight container.

Making Natural Printmaking Ink

You can also create your own natural printmaking ink using similar methods. A simple ink recipe includes:

Ingredients:

• 1 tsp natural pigment
• 1 tsp linseed oil or walnut oil
• A small amount of beeswax (for thickness)
• A few drops of clove essential oil (to prevent mold)

Instructions:

1. Melt the beeswax in a double boiler.
2. Stir in the pigment until fully incorporated.
3. Slowly add linseed or walnut oil, stirring until smooth.
4. Add a few drops of clove oil for preservation.
5. Store in an airtight container and use for printmaking applications.

Safety Considerations When Making Natural Paints

While natural paints are generally safer than synthetic alternatives, it’s still important to take precautions:

1. Wear a Mask – Avoid inhaling fine pigment particles, especially when grinding minerals or sifting powders.
2. Gloves & Skin Protection – Some natural pigments, like walnut husks, can stain or irritate skin. Wear gloves when handling strong pigments.
3. Ventilation – Work in a well-ventilated space when boiling plant materials or using alcohol-based extractions to avoid inhaling fumes.
4. Test for Allergies – Some plant-based pigments can cause allergic reactions. Test a small amount on your skin before extensive use.
5. Avoid Contaminants – Ensure that foraged materials are free from pesticides, mold, or pollutants.
6. Use Non-Porous Tools – Avoid using wooden or porous materials that can absorb pigment and introduce bacteria over time.
7. Label and Store Properly – Clearly mark pigment jars and keep them separate from food items to prevent accidental ingestion.

Using and Storing Natural Paints

• Storage: Natural paints, especially water-based ones, don’t contain preservatives and can spoil quickly. Store in the fridge and use within a week, or add a natural preservative like clove oil. You can store the pigments in powder form much longer, so only process what you need.
• Application: Expect some variation in color depending on how the paint dries. Test swatches before committing to a final piece.
• Layering: Natural paints tend to be more transparent than synthetic paints, so build up layers for richer tones.

Final Thoughts

Creating your own natural paints is a rewarding and eco-friendly alternative to store-bought options. Not only does it reduce waste, but it also deepens your connection to the materials you use and the world around you. Whether you’re a painter, mixed-media artist, or just love experimenting, making natural paints is a step toward a more sustainable and mindful art practice.
