I guess part of the problem is that there are only three color receptors, rather than thousands, so there is less reason to represent commonalities between them. That said, we do talk about “warm” and “cool” colors, which mainly seems to refer to how much blue is mixes in them. So that seems a bit like a one-dimensional “heat” scale, with blue on the cold end and red/green on the work end?
