If a sample is called yellow-orange but contains more red, what is the naming problem?

Correct answer: Its bias is likely toward red-orange

A tertiary colour name should agree with the mixture’s dominant visual bias. If the sample contains noticeably more red than yellow, its appearance may shift toward red-orange rather than yellow-orange. Therefore, option B identifies the naming problem. It does not become blue-green, a primary colour, or a neutral colour merely because the proportion changes.
