Blue can mean gray
The Cat Fanciers Association explains that breeders and geneticists often call a gray-looking cat blue. The term is a coat-color convention, not a claim that the fur resembles a bright blue object. A useful everyday description can retain both words rather than correcting a person out of their own observation.

Red can mean orange
The association also uses red for an orange-looking coat and cream for a lighter yellow or beige appearance. This is a vocabulary bridge, not a tool for assigning a formal show color. A photograph, screen setting or written impression does not supply an official classification.

Names depend on the setting
UC Davis notes that registries may name the same phenotype differently. Some brown and pale-color names also vary across breeds in the association guide. If you are completing a specific form, use that forms definitions or ask its administrator instead of assuming a glossary is universal.

Describe rather than overrule
A note can read gray-looking coat, specialist term possibly blue, uncertain under this light. That keeps the observation separate from the candidate label. This site does not alter a registration record, certify a show entry or tell a rescue which official category it must use.
