The molecules that make up all natural and artificial colors are called “pigments”. Pigment molecules act with a certain energy. There is an effect of light at all stages of color formation. There is also a relationship between pigments and light. Sunlight is important and necessary for color molecules or pigment molecules in living things.
The properties sought in the production of pigments are as follows; resistance to ultraviolet rays, heat stability, toxicity, coloring strength, staining, distribution, transparency or opacity, resistance to alkalis and acids, reactions and interactions between pigments.
Most of the organic pigments used today are petroleum-derived and synthetic. In the production of these, a large amount of toxic waste occurs. Synthetic inorganic pigments are produced as a result of simpler chemical reactions. Natural inorganic pigments consisting of minerals are found in soil and rocks and have been used in the form of dyestuffs for thousands of years. Pigments are used in architectural projects with connectors such as lime, cement, lime juice, casein, wax and oil and are involved in paint production. Pigments can be mixed to create infinite hues.
Organic pigments may be plant or animal-derived, while inorganic pigments may be salt or metal oxide. Pigment molecules work with a certain energy. All steps of color formation have the effect of light. Colors appear as pigments selectively absorb and reflect certain wavelengths of UV light.
When selecting pigment, the tone and desired color depth, the necessary technical characteristics such as light disease, basic colors and the species obtained from them, environmental laws and cost factors should be taken into consideration.
