Instead of colour wheels, why not provide an option where you search for colours based on name, and it gives you a pallet that best matches it. Like a mini google search.
So if you want the colour that you notice from an apple.
You type apple, and you get a set of pallet that generally is associated with apple, e.g. apple red, apple green, apple brown roots. etc...

This would require a database, but you can make this offline or online. Online has the advantage of user up- datable pallets. But a mix of both would be good.-- mofosyne, Jun 03 2015 Recently I found myself wanting this kind of functionality in a *text* editor. Like "Search document for hex color codes similar to _____ (threshold ____ %)"-- Spacecoyote, Jun 05 2015 random, halfbakery
