Natural Pigments: The Easy Guide to Crafting Vibrant Colors from Plants & Flowers (2025)

Art is good for the soul, but what about the environment?

According to Nietzsche, art is the highest expression of life. Most people would also probably agree that art is a defining characteristic of the human race, if not the defining one. 

Unfortunately, modern art also contributes to a world drowning in waste and toxic chemicals.

The toxic byproducts of certain oil and acrylic paints are nothing to sneeze at. Not only can they be harmful to you, the artist, but the environment, too, especially marine life.

Luckily you can create wonderfully vibrant paints and dyes from plants and flowers. Natural pigments are environmentally friendly, safe, and highly versatile, plus they’re pretty easy to make.

In this guide, we’ll look at what plants and flowers make the best pigments for painting, how to make your very own pigments, the benefits of using natural pigments, and some potential disadvantages.

What Are Plant Pigments?

Natural pigments have been used since prehistoric times. They can be derived from minerals and rocks like clay and azurite but also from animals, plants, roots, fruits, and flowers.

In fact, some of the richest pigments in nature can be found in your backyard. In spring, summer, and fall, flower and plant dyes can offer you a wide range of vibrant colors.

From painting a beautiful landscape to dyeing fabrics to staining wood, natural pigments can be used for all kinds of DIY projects.

All you need is a little time, a few rudimentary tools, and of course, plants and flowers of your choice!

While almost all plants and flowers can give you some pigment, not all will produce those rich, distinctive colors needed for painting. But the following flowers and plants will.

• Oranges: coreopsis flowers, madder root, carrots, rhubarb root
• Yellows: safflower, dandelion flowers, onion skins, marigold flowers, weld
• Reds: madder root, roses
• Purples/Pinks: red cabbage, beetroot, blackberries, elderberries
• Blues: indigo, blueberries, woad, red cabbage
• Greens: spinach leaves, nettle, comfrey, grass, matcha
• Browns: coffee, leaves, black walnut hulls

This list is certainly not exhaustive, and there are many more plants, vegetables, fruits, and flowers that can give vibrant paint and dye pigments out there!

However, it’s important to keep in mind that botanical pigments can be very unpredictable. Just because a plant is green, for example, does not mean it will produce a green pigment (more often than not, it will be yellow, brown, or yellowish-greenish). Also, some colors will change slightly, sometimes even dramatically, once they dry.

How to Make Your Own Botanical Pigments

Painting with botanical pigments is a process of discovery, which is why we highly encourage experimenting with different plants and flowers and playing with the extraction process. While not difficult or complex, the process of extracting pigments from plants requires time and attention to detail.

As mentioned, countless flowers, fruits, vegetables, and roots can give lovely paints, but it’s best to start with what you can find in your backyard, nearby park, or even supermarket. Today, we’ll focus on making botanical pigments from red cabbage.

How to Make Natural Pigments from Red Cabbage

Red cabbage is one of the best sources of natural pigment due to its high amount of anthocyanins. Anthocyanins are powerful antioxidants that are great for our health, but they also give the cabbage a wonderful purplish color you can use for painting.

Due to a high content of anthocyanins, red cabbage can give several different colors, including purple, green, pink, yellow, and blue, depending on the pH modifiers you use and how dry the pigment gets.

Another great thing about making pigments from red cabbage is that it’s super easy to find. If you don’t have it in your garden, a grocery store near you is certain to have it. You also don’t need a lot to make plenty of pigment. Use most of the cabbage for your favorite dish and scraps for making pigment.

What You’ll Need

• Several handfuls of shredded red cabbage
• A saucepan or pot
• Water for cooking red cabbage
• Three small jars
• Cheesecloth/fine mesh strainer
• Powdered or liquid gum Arabic
• A few drops of clove/oregano/thyme essential oil
• Baking soda
• White vinegar

Method – Making Pigments from Cabbage

• Finely chop several leaves of red cabbage or place them in a blender.
• Place the chopped cabbage in a pot and add water so the cabbage is completely submerged.
• Put the pot on the stove and let it simmer on low heat for about 3 to 4 hours.
• Strain the mixture over several small jars using a cheesecloth or strainer and press the liquid from the cabbage pulp.
• Add a drop or two of the essential oil you chose to each jar to prevent molding.
• Add several drops/couple of teaspoons of gum Arabic to each jar to make the pigment bind to the paper later on.
• Add several drops of white vinegar to the first small jar to turn the color into a lighter pink.
• Add some small pinches of baking soda to the second jar to turn the color into a darker blue.
• Leave the last jar as is, and you should have a regular purple color.

How to Make Natural Pigments from Avocado

Avocados are not only delicious and nutritious but also a fantastic source of natural pigments. The pits and skins, often discarded, can be transformed into beautiful pink and orange hues. This eco-friendly process allows you to repurpose avocado waste into vibrant, non-toxic paint pigments.

What You’ll Need

• Avocado pits and skins (from 3-4 avocados)
• A large pot
• Water
• Strainer or cheesecloth
• Small jars for storing pigment
• Gum Arabic (powdered or liquid)
• A few drops of clove, oregano, or thyme essential oil
• Optional: white vinegar or baking soda for pH adjustment

Method – Making Pigments from Avocado

1. Clean the avocado pits and skins thoroughly, removing any remaining flesh.
2. Place the pits and skins in a large pot and cover with water.
3. Bring the water to a boil, then reduce heat and simmer for 1-2 hours. The water should turn a deep pink or reddish-brown color.
4. Strain the liquid through a cheesecloth or fine mesh strainer into small jars.
5. Add a few drops of essential oil to each jar to prevent mold growth.
6. Mix in gum Arabic to help the pigment bind to paper when used for painting.
7. Optional: Experiment with pH modifiers. Add a few drops of white vinegar for a more pinkish tone or a pinch of baking soda for a deeper reddish hue.
8. Let the pigment cool completely before use.

The resulting pigment can range from soft pink to deep maroon, depending on the avocados used and any pH adjustments made. Like other natural pigments, avocado-derived colors may change slightly as they dry, offering an exciting element of surprise to your artwork

Remember that natural pigments can be unpredictable, so it’s best to experiment with different batches to achieve your desired color. The tannins in avocado pits act as a natural mordant, which can help the pigment adhere better to surfaces, especially when used for dyeing fabrics

By using avocado pits and skins for pigments, you’re not only creating unique colors for your art but also contributing to waste reduction and sustainable art practices.

How to Make Natural Pigments from Pomegranate Rinds

Pomegranate rinds, often discarded after enjoying the fruit, can be transformed into a versatile range of yellow tones for natural pigments. Rich in ellagic tannins, pomegranate extract produces warm yellow-brown shades that are perfect for eco-friendly art projects.

What You’ll Need

• Pomegranate rinds (from 3-4 pomegranates)
• A large pot
• Water
• Strainer or cheesecloth
• Small jars for storing pigment
• Gum Arabic (powdered or liquid)
• A few drops of clove, oregano, or thyme essential oil
• Optional: iron sulfate for color variation

Method – Making Pigments from Pomegranate Rinds

1. Remove the rinds from the pomegranates and chop them into small pieces.
2. Place the chopped rinds in a large pot and cover with water.
3. Bring the water to a boil, then reduce heat and simmer for 1-2 hours until the water turns a rich yellow-brown color.
4. Strain the liquid through a cheesecloth or fine mesh strainer into small jars.
5. Add a few drops of essential oil to each jar to prevent mold growth.
6. Mix in gum Arabic to help the pigment bind to paper when used for painting.
7. Optional: For darker shades, add a small amount of iron sulfate to create cement greys and moss greens.
8. Let the pigment cool completely before use.

The resulting pigment can range from soft yellows to green-yellows, depending on the pomegranates used and any additives. Pomegranate rind extract not only provides color but also improves the light and wash fastness of other dyes it’s combined with, making it an excellent choice for mixed media projects.

How to Make Natural Pigments from Spirulina

Spirulina, a blue-green algae, is renowned for its ability to produce striking blue hues thanks to its phycocyanin content. This versatile pigment can be used to create vibrant blues and greens for various artistic applications.

What You’ll Need

• Spirulina powder (food-grade)
• Distilled water
• Small mixing bowl
• Whisk or small blender
• Fine mesh strainer or coffee filter
• Small jars for storing pigment
• Gum Arabic (powdered or liquid)
• A few drops of clove, oregano, or thyme essential oil
• Optional: lemon juice or baking soda for pH adjustment

Method – Making Pigments from Spirulina

1. Mix 2 tablespoons of spirulina powder with 1/4 cup of distilled water in a small bowl.
2. Whisk thoroughly or blend for a few seconds to create a smooth paste.
3. Let the mixture sit for 15-20 minutes to allow the pigment to fully dissolve.
4. Strain the liquid through a fine mesh strainer or coffee filter into a small jar.
5. Add a few drops of essential oil to prevent mold growth.
6. Mix in gum Arabic to help the pigment bind to paper when used for painting.
7. Optional: Adjust the pH with a few drops of lemon juice for a more turquoise tone or a pinch of baking soda for a deeper blue.
8. Let the pigment settle for a few hours before use.

The resulting pigment will offer vibrant blues to greens, depending on the concentration and any pH adjustments made. Spirulina-derived colors are not only beautiful but also rich in antioxidants, making them a healthy choice for artists concerned about exposure to synthetic pigments.For both pomegranate and spirulina pigments, remember that natural colors can be unpredictable and may change over time. This variability adds a unique and dynamic quality to your artwork, embracing the organic nature of these eco-friendly pigments.

Spirulina-derived colors are finding applications in various industries, from confectionery and beverages to natural makeup products and eco-friendly textiles

Now that you have four different colors, it’s time to start painting!

Again, keep in mind that natural pigments can be unpredictable. Not only will the color depend on the type and amount of pH modifiers you use, but it will also change with time. What starts as blue might turn to green in a day or two. And what begins as green might change to yellow after several weeks.

How to Use Plant Pigments

The best thing about using natural pigments – aside from the fact they’re zero-waste – is that there is so much room for fun experimentation, and the possibilities are endless.

For example, for a base green color, you can steep spinach leaves in hot water (the older the leaves, the richer the color) and add matcha powder to the mix. Add some turmeric to the mixture, and you’ll get a more yellow-green pigment. Add a little coffee, and you’ll get a much darker seaweed color.

Coreopsis flowers can give a variety of pigments, too. The longer you steep them in boiling water, the darker the color will be. If you add some bicarbonate soda to the mix, the color will become a darker orange or red. Want to turn it back to yellow? Add a few drops of lemon!

Some plants give incredibly vibrant colors with little effort (like red cabbage), while others need to be boiled, crushed, and mixed with other plants or spices to produce a good pigment (such as spinach).

Whatever plants you choose for your pigments, you’re sure to get lovely, vibrant colors with some experimentation. You can use these to create unique, eco-friendly artworks such as watercolor botanical illustrations, textured paintings, and nature-inspired abstracts. You can also use natural pigments to paint on unconventional surfaces, such as wood or fabric.

Have fun and experiment!

The Benefits of Using Natural Pigments

Natural dyes are not only rich and complex, but they’re also much kinder to our skin, home, and the environment.

Sure, synthetic dyes are more opaque, easier to obtain, and undoubtedly produce more consistent results. But at what cost?

Acrylic paints, for instance, are overwhelmingly not biodegradable. Like all plastics, acrylic paints can be harmful when they break into microplastics, which is especially harmful to marine life. And while most oil paints are perfectly safe when used alone, if you use solvents to thin the paint (which most artists do), even oil paints will release toxic chemicals.

Natural pigments, on the other hand, are non-toxic and fully biodegradable, making them eco-friendly. They can also create colors not found in synthetic pigments, helping you create truly unique artwork.

The main disadvantages of using natural pigments are that they provide inconsistent results and that they have a shorter shelf life than synthetic ones. Still, the benefits far outweigh the disadvantages; nothing beats making art with nature!

Wrapping Up

In conclusion, if you want to produce eco-conscious, zero-waste art, it’s best to experiment with plant paints. Of course, if you don’t want to spend time harvesting and preparing plants and then experimenting with the extraction process, you can always opt for ready-made art. There are plenty of eco-friendly paintings for sale that are less polluting and less toxic than most mainstream artwork.
