The color that makes you look good (idea)
|Carole Jackson's books divide people into four categories (winter and summer, which are cooler colors, and spring and autumn, which are warmer colors) and advises how to figure out which group you're in and which colors look best on each group. The winter colors seem to work very well on me, and they definitely matched the prejudices for some colors and against others that I'd had throughout my life.
(However, some readers feel that the groups, to quote a review at Amazon.com, "don't work very well for light-skinned redheaded Caucasian women, dark-skinned women of African descent, native North Americans, and women whose ancestors are from South Asia, the Pacific or parts of the Middle East.")
It's has turned into kind of a franchise now, with more stuff in the series by different authors and cosmetic brands that have tie-ins with the idea, but the original books are still quite interesting.
