I'm currently working on a design for a product filter, and one of the attributes will be color. Products will have any of several dozen specific colours, but it makes more sense to give users a handful of "basic" colors to filter instead of listing every one.
Amazon and eBay do this already. A user might select Green, and see products with color set as Green, Light Green, Olive, etc.
It's tough to define the shortest list to give users the right flexibility, but I've come up with the following:
Black, White, Grey, Brown, Red, Pink, Orange, Yellow, Off-White, Green, Blue, Purple, Gold, Silver, Multicolour, Transparent, Not specified
Do these basic colors swatches make the most sense to display to users, or is there a better list?
