Foldable Digital Compact that Identifies Makeup Brands and Shades

This technology pertains to a digital compact that can fold open and can tell you what type of makeup someone else is wearing, simply by analyzing either the chemical makeup of the makeup, by applying a sample to it, or by taking a photograph with spectral analysis. This would determine what shade of makeup is being used, in addition to what type or brand. More complex devices could determine all the different types of makeup that someone is wearing. More simple devices could be like digital pagers that people could share what brand(s) and makes of makeup they are using. The devices could also automatically order the makeup for new customers.
