Optical Properties Of Oil Painting Pigments

Color Saturation
Color saturation refers to the purity and vividness of a pigment's color. The color saturation of oil painting pigments mainly depends on the quality of pigments and the performance of blending agents. High quality pigments and suitable blending agents can endow oil painting pigments with high saturation color expression ability, making the works more vivid and realistic.
Gloss
Glossiness refers to the ability of a pigment to reflect light on its surface after drying and forming a film. Different types of oil painting pigments have different glossiness expressions. White pigments such as titanium dioxide usually have higher glossiness, while some mineral pigments may present a matte effect. Artists can choose appropriate glossiness according to their needs during the creative process to express different textures and atmospheres.

The relationship between transparency and coverage
There is a close relationship between the transparency and coverage of oil painting pigments. Colors with good transparency will inevitably have weak coverage, and vice versa. This relationship allows artists to achieve rich color layers and texture expression by adjusting the transparency and coverage of pigments during the creative process. For example, when creating images that require transparency, artists can choose pigments with high transparency for cover dyeing; When emphasizing color hierarchy and contrast in a picture, one can choose pigments with strong covering power for layering.
