Cosmetic compositions exhibiting characteristic first derivative spectral curves and associated methods

Cosmetic compositions and cosmetic compositions that have been adapted for delivery to provide applied cosmetic compositions that have a spectrophotometric curve, wherein a first derivative of the spectrophotometric curve comprises: a) a maximum peak in the region of from about 430 nm to about 520 nm occurs at a wavelength not greater than about 480 nm; b) a maximum peak in the region of from about 420 nm to about 650 nm occurs at a wavelength of from about 570 nm to about 630 nm; and c) a minimum valley in the region of from about 520 nm to about 580 nm has a %R/ of less than or equal to about 0.03, wherein R is reflectance and is wavelength, and wherein the cosmetic composition comprises a mixture of at least two colorants, wherein a first derivative of a spectrophotometric curve of each of the individual colorants does not exhibit (a), (b) and (c). Methods for providing such compositions comprise adding colorants to a cosmetic composition to provide the composition with a spectrophotometric curve as described.
