Identify pigments on tubes

In this article, we'll explore the different types of pigments used in fine art painting, their characteristics and how to recognize them on paint tubes. Understanding pigments is a fundamental step for any art enthusiast or professional looking to deepen their knowledge in the field of painting.

Quality paints always indicate their composition on the back of the tube. If it doesn't, don't buy it - it's too cheap.

Which pigments to choose

• Choose a pure pigment composition, i.e. composed of a single pigment, except for certain yellows, on condition that no white is added.
• Colors composed of several pigments can easily be obtained by mixing.
• By opting for a pure composition, you'll be able to control your blends and easily respect the golden rule of never mixing more than three pure colors together.
• Beware of tubes stamped "Primary Blue" or "Primary Magenta", as they usually contain white. Look closely at the label.
  For primary blue, for example, take phthalocyanine blue (PB15).

The different types of pigments and their properties

Minerals

Mineral pigments are inorganic pigments extracted from natural minerals such as iron oxide, umber or titanium white. They offer high chemical stability and excellent lightfastness, making them ideal for paints designed to last over time. For example, iron oxide is widely used for its warm, natural hues, while titanium white is appreciated for its luminosity and opacity. These mineral pigments have been used since ancient times to create durable, timeless works of art.

Organics

In contrast to mineral pigments, organic pigments are complex chemical compounds derived from organic materials such as plants, animals or petroleum derivatives. They offer a palette of bright, vivid colors, ideal for contemporary art paints. For example, phthalocyanine-based green pigments offer a range of shades from turquoise to emerald green. However, these organic pigments can be less stable over time and sensitive to light, sometimes requiring special precautions to ensure their longevity.

Synthetics

Synthetic pigments are pigments created artificially in the laboratory, offering a wide variety of colors and properties. Cadmium red or phthalocyanine blue are examples of synthetic pigments widely used in the paint industry. Their high chromatic purity and stability make them popular choices for many artistic applications. Synthetic pigments can also be used to produce customized colors and unique effects, offering artists limitless creative freedom.

Environmental impact of paint pigments

1. Environmental impact of synthetic pigments

Synthetics used in paint have a significant environmental impact. Their manufacturing process can generate toxic chemicals that contaminate air, water and soil. For example, some synthetics contain heavy metals such as cadmium, lead or chromium, which are hazardous to human health and the ecosystem. When released into the environment, they can cause long-term damage, affecting biodiversity and water quality.

What's more, the production of synthetics often requires the use of non-renewable resources and generates toxic waste that is difficult to dispose of. These environmental impacts must be taken into account when choosing which paints to use, in order to minimize the ecological footprint of our artistic activities.

2. Advantages of natural and organic

Natural and organic products offer a more environmentally-friendly alternative to synthetics. They are generally made from raw materials of plant, mineral or animal origin, and have the advantage of being biodegradable and non-toxic. For example, pigments such as ochre, charcoal or indigo can be extracted from natural sources with no negative impact on the environment.

By using natural and organic pigments, artists can help preserve biodiversity and reduce pollution. What's more, these pigments often offer subtle nuances and unique textures, adding an artistic and sensory dimension to their works.

3. Initiatives to promote sustainable pigments

With growing concern about the environmental impact of pigments used in paint, more and more initiatives are being launched to promote sustainable alternatives. Some companies are turning to more environmentally-friendly production practices, using clean technologies and renewable raw materials to manufacture eco-friendly pigments.

In addition, artists and organizations are campaigning to raise awareness of the importance of choosing paints based on sustainable, environmentally-friendly pigments. Eco-labels and certifications are also being introduced to guide consumers towards more responsible products, encouraging a transition to a greener, more sustainable paint industry.

Tips for choosing eco-friendly paints

Opt for natural and organic pigments

Natural and organic products are sustainable alternatives to synthetics. They are often derived from renewable raw materials such as plants, minerals or insects. By choosing paints containing these pigments, you're promoting environmentally-friendly and health-friendly production. What's more, naturals offer a rich and varied palette of colors, bringing an authentic and unique touch to your artistic creations.

Check environmental certifications

Many paint brands are committed to using environmentally-friendly pigments. When buying tubes of paint, check for certifications such as "Ecological Label" or "Certified Organic Product". These labels guarantee that the pigments used have been produced sustainably, without toxic or polluting substances. By choosing certified paints, you're helping to preserve biodiversity and reduce your ecological footprint.

Choose those that are non-toxic and biodegradable

Non-toxic, biodegradable paints are essential to protect your health and the environment. By avoiding paints containing heavy metals or harmful chemical compounds, you limit the risks of poisoning and pollution. Those that are biodegradable decompose naturally without harming the ecosystem, contributing to more sustainable artistic production. Opting for paints based on non-toxic, biodegradable pigments is a responsible choice to preserve our planet for future generations.
