Cool Colors
"Cool" colors lean toward blue and green, and the word is also used for a version of any hue shifted slightly toward blue. The register lists 15 color names containing "Cool" (including forms like "Cooled"). Some are cool by nature, such as Cool Mint, Cool Blue and Cool Grey; others apply the idea to warm hues, so Cool Red is a bluish crimson. Cool Copper is the exception that proves names are chosen, not measured: despite the label, it is a bright metallic orange. About half of the names are light tints, including Cool White, a white with a faint blue cast that also describes a type of lighting. The opposite idea is collected in the Warm list.
