I think it's an interesting concept when a store limits the colour scheme of its goods. The White Company, a UK retailer, was built on this premise and has been in operation for a number of years selling mainly white linens and accessories.  This trend appears to be gaining popularity in America now with stores like Sparrow & Co selling home wares and accessories in muted shades and a restricted colour range.

While not everyone will embrace this trend, I can see how it could simplify the choice for the consumer and make curating a store's inventory much easier, because if a product doesn't meet this very strict criterion, it simply won't be eligible for sale.
