Try a clothing store with exact color hex codes on the tags of all garments, and, software in which someone's skin tone and eye color are matched with one's appropriate seasonal color. Such a store would diagnose/prescribe a shopper's acceptable colors and said shopper would choose items using the color hex code on the tags.

This could be an entirely online operation, too, given a smartphone app and a web store which provided access to the color codes for each of the garments.

See the book "Color for Men" by Carol Jackson for more details on seasonal color theory.

Send me a couple hundred if it ever gets off the ground.
