Alexandra, you've hit on something important here: any given colour name can actually represent a whole range of actual colours! I would have thought "honeysuckle" was some shade of yellow, more golden than lemon, but what shade, exactly? Same goes for all the colour words. They only narrow it down, to a greater or lesser degree -- like, tomato is a more orangey-red than maroon, but how much more orangey?
And then there's the perplexing issue of whether or not the colour I see is the same as the colour YOU see, when looking at the same object.
It's all very subjective. Good medicine analogy, btw. (Although there must be at least an element of belief to it, if it's subjective -- it's like assessing an artwork. I don't always agree with the critics, and they don't always agree with each other).
