Definition - What does Chroma mean?

Chroma is a term used in coatings to describe their ability to withstand harsh environments through the selection of color intensity and reflectiveness. It is used to identify special coatings with unique formulas and supreme characteristics toward efficiency, protection and durability. More specifically, chroma is the colorfulness of a specific color relative to a white reflection and can be derived from the Munsell constant hue chart, which depicts color strength.

Corrosionpedia explains Chroma

Color pigments and surface texture or appearance control the level of illumination on the surface of a substrate. A coating high in chroma is the best for reflecting infra-red and UV rays. It operates on the lightness levels in a specific hue. In the Munsell chart, chroma changes as one goes away from the center of the Munsell constant hue chart to the right.

This means that in a hue, the colors vary since the ones on the periphery are pure, saturated and intense in terms of reflection. Ceramic and inorganic paints or coats are made to produce chroma pigments, which assist in corrosion and fading resistance.

Therefore, the chroma series used in painting is designed to produce a reflective coating that reduces fading and scaling. In the end, this makes the surface more resistant to corrosion.
