The Ancient History of Natural Colours

Natural dyes have been used for many thousands of years. Plants, minerals, and insects were used to dye textiles, cosmetics, and even food in cultures as diverse as Egypt, India, Greece, China, and Native Americans. Indigo, derived from the Indigofera tinctoria L. plant, was highly valued in ancient India, while Tyrian purple, derived from sea snails, was considered a luxury in Roman culture. Not only did the ancient Egyptians decorate with plants like furious for red and safflower for yellow, but they also used them for religious rituals. These colors were valued not only for their aesthetics, but also for their symbolic meaning. For example, in many cultures, red symbolised power and protection, whereas green represented fertility and rebirth. Such symbolism emphasises the deep connection between humans.

Sources of Natural Colors from Botanical Wealth

Natural colors from plants come from a range of biochemical compounds, including flavonoids, carotenoids, and anthocyanins. These compounds absorb light at different wavelengths, producing diverse colors.

Anthocyanins: These are water-soluble pigments that produce the red, purple, and blue colors found in many fruits and flowers, such as blueberries, grapes, and purple cabbage. Japanese Indigo produces blue colors. A blue pigment also derived from the algae Spirulina.

Carotenoids: Carotenoids, which produce yellow, orange, and red hues, are responsible for the vibrant colors of carrots, tomatoes, and marigold flowers. They aid in photosynthesis and protect plants from photodamage.

Chlorophyll: Chlorophyll is a naturally occurring green pigment found in plants and algae that is necessary for photosynthesis. It absorbs light, especially blue and red wavelengths, and reflects green, giving plants their distinct color. Chlorophyll comes in two forms: chlorophyll a and chlorophyll b, both of which help to capture sunlight. In addition to its natural function, chlorophyll is used as a natural food coloring and is valued for its antioxidant properties in health products.

Flavonoids and Tannins: These compounds contribute to the yellow, orange, and brown tones in plants. For example, tannins found in tree bark and leaves produce earthy tones and were historically used in the leather tanning process.

Betalains: Betalains, which are primarily found in the Caryophyllales order of plants (including beets), provide a vibrant range of reds, purples, and yellows while also acting as powerful antioxidants.

Extraction Methods of Natural Dyes

The process of extracting natural dyes from plants has evolved over centuries. Traditional methods involved boiling plant materials such as leaves, flowers, or roots in water, sometimes with the addition of salts or acids to fix the color to textiles or other surfaces. Modern techniques have evolved to include more efficient and sustainable extraction processes, such as:

• Supercritical fluid extraction: A technique that uses CO₂ to extract pigments without damaging the plant compounds.
• Microwave-assisted extraction: This method reduces the time and energy required to extract color compounds while maintaining their integrity.
• Enzymatic extraction: Using enzymes to break down plant cell walls, making it easier to extract pigments without the use of harsh chemicals.

Applications of Natural Colours

1. Textiles and Fashion
The fashion industry is a major consumer of synthetic dyes, which have been linked to environmental pollution and human health concerns. Natural plant dyes provide an environmentally friendly alternative. Indigo for blue jeans, turmeric for yellow garments, and madder for red hues are just a few of the ways botanical wealth is being used to create sustainable fashion.

Natural dyes are becoming more popular among artisans and designers as a means of producing distinctive, colorful textiles. These dyes frequently produce soft, earthy tones that are difficult to replicate with synthetic colors, giving garments a natural and authentic appearance. The challenge, however, is scaling up the use of natural dyes to meet mass production demands, as natural dyes can be more labour-intensive to extract and process.

2. Food and Beverages
Natural colorants are increasingly used in the food industry as consumers demand healthier and cleaner products. Synthetic food dyes have been associated with potential health risks, leading to the exploration of plant-based alternatives. For example:

• • Beetroot provides a rich red color for products like juices, yogurts, and sauces.
  • Turmeric offers a vibrant yellow, often used in curries, mustards, and snacks.
  • Arthrospira platensis Gomont or Spirulina (a type of algae) has become popular for producing natural blue hues in candies and beverages.
  • These natural colorants also offer the added benefit of antioxidant and anti-inflammatory properties, making them a healthier alternative to synthetic dyes.

3. Cosmetics and Skincare
Botanical colors are becoming more popular in the cosmetics industry as consumers demand more natural and organic options. Annatto, Saffron, and Henna are among the ingredients used to create a variety of colors for makeup, hair dyes, and skincare. Plant-based pigments are popular in the beauty industry because they often have additional skin benefits, such as moisturising and anti-inflammatory properties.

4. Pharmaceuticals
Certain plant-derived pigments are used in pharmaceuticals for both their color and therapeutic properties. Anthocyanins and carotenoids, for example, have been investigated for their antioxidant and anticancer properties. Natural colorants found in botanicals can also be used as quality control markers in medicinal formulations.

Botanical Sources of Natural Color

Botanical sources of natural color are plants, flowers, fruits, and other natural materials that produce pigments used to color food, textiles, cosmetics, and other products. Here are some common sources:

• Hibiscus sp.: Produces red to purple hues, often used in beverages and cosmetics.
• Saffron (Crocus sativus): Yields a rich yellow color and is used in food and cosmetics.
• Marigold (Tagetes patula): Used for yellow to orange hues, especially in food coloring and natural dyes.
• Butea monosperma (Lam.) Kuntze: It gives orange yellow color, local people of Jharkhand are using this in Holi festival.
• Beetroot (Beta vulgaris): A rich source of red-purple pigment (betanin), used in food and beverages.
• Blueberries (Vaccinium sp.): Provide blue and purple hues due to anthocyanins.
• Pomegranate (Punica granatum): Produces a deep red color, primarily due to anthocyanins and tannins.
• Carrot (Daucus carota): Orange colour comes from beta-carotene.
• Red Cabbage (Brassica oleracea capitata f. rubra): A natural source of purple and blue due to its high anthocyanin content.
• Turmeric (Curcuma longa): Provides a vibrant yellow color due to curcumin, widely used in foods and fabrics.
• Annatto (Bixa orellana): Derived from the seeds, gives a yellow to orange hue and is used in cheese and butter coloring.
• Chlorophyll (from green plants): Provides green pigment, used in cosmetics and foods.
• Carmine (from Dactylopius coccus Costa, 1835 insects): While technically an insect-based colorant, it is often used in conjunction with botanical for pink to red shades.
• Logwood (Haematoxylum campechianum): Produces shades of purple and blue, often used in textile dyeing.
• Spirulina (Arthrospira platensis Gomont): A blue-green algae that yields blue pigments, used in food coloring.

Sustainability and Environmental Impact

The negative impact of synthetic dyes is a major factor driving the shift towards natural dyes. Synthetic dye production uses toxic chemicals, petroleum-based products, and a lot of water, which pollutes water bodies and harms ecosystems. Natural dyes, on the other hand, are biodegradable and more environmentally friendly. However, the widespread use of natural dyes presents challenges. Large-scale plant harvesting for dyes has the potential to deforest and deplete valuable plant species. Sustainable farming practices, such as regenerative agriculture and permaculture, will be critical for ensuring that natural dyes do not harm biodiversity.
