The closest equivalent I can get to this and still understand it is by thinking of browsing the colour catalog and trying to choose a colour and shade.

We (mostly) all can identify green, blue, brown, black, white etc and then we can identify light blue, dark blue within that, but go to some of the more subtle shades and then it becomes much more difficult to identify. The colour catalogs have all sorts of descriptions, how many of those do people actually remember - unless they are particularly important to them - not many. Ask the average person on the street to identify harvest pink or autumn gold, and they wont have a clue. So, given that, how can the average person in the street be expected to identify anything other than the most basic of things, unless it is important to them and to most, it just isn't important.
