Definition
Chromatism refers to an unusual or abnormal coloration, often used in a biological or medical context. It describes the presence of colors that are not normally there or are present in an excessive or distorted manner. Think of it as a deviation from the typical color pattern, like a bruise or a birthmark. It's not just about having color, but about having color that's out of the ordinary. Imagine seeing green skin on a person who isn't wearing makeup; that would be an example of chromatism.
