History of Phthalo Blue
Phthalo Blue is a bright, intense blue color that is a part of the phthalocyanine family of pigments. It is one of the most widely used pigments in the world, and it is prized by watercolor artists for its ability to create rich, transparent washes and intense, vivid colors.
Phthalo Blue was first developed in the 1930s as a replacement for traditional pigments that were prone to fading and other forms of degradation. Unlike traditional pigments, phthalocyanine pigments are synthetic compounds that are made through chemical reactions. This allows them to be precisely engineered for specific color properties and performance characteristics.
Phthalo Blue is highly versatile and can be used to create a wide range of colors when mixed with other pigments. It is also highly lightfast and durable, making it a popular choice for artists who want their paintings to last for generations.
Fun fact: Phthalo Blue is often used as a colorant in plastics, textiles, and other materials due to its intense color properties and lightfastness. It is also used as a dye in the textile industry, where it is prized for its ability to create vivid, long-lasting colors.
How watercolor paint is made
Watercolor paint is typically made from a few simple ingredients:
- pigments
- binders
- water

The pigments used in watercolor paints can be organic or inorganic compounds, such as minerals or synthetic chemicals. These pigments are finely ground and then mixed with a binder, which helps the pigment particles adhere to the paper when the paint is applied.
The most common binder used in watercolor paints is gum arabic, a natural resin extracted from the sap of the acacia tree. Gum arabic is mixed with the pigment to create a thick paste, which is then combined with water to create the final paint.
Other additives may be added to the paint to improve its performance or create specific effects. For example, some watercolor paints may include wetting agents to help the paint spread more evenly on the paper, or preservatives to extend the paint’s shelf life.

Watercolor paints are available in a wide range of colors and textures, from transparent washes to opaque and granulated pigments. Different
manufacturers may use slightly different formulations or ingredients in their paints, which can affect the quality and performance of the paint.
