In linguistics this sort of thinking comes from 'basic color term' theory, which lays out heuristics for deciding if a word for a color in a given language is 'basic'. 2 things going against these blue-green terms are:
* They refer to specific objects (a duck and a stone), eventually these referents can be transcended though, like with the case of orange.
* Their frequency is roughly similar to each other (along with cyan, aqua, etc.), so there's no one term for this range (e.g. there's no doubt in a corpus of English that red is the basic color term for its spectrum).
