Companies are finally recognizing what medical laser manufacturers have known for years: there is no single color of “skin tone.” In cosmetics, skin care, and clothing, companies are broadening their spectrum to broaden their customer base. Matching a skin color is difficult because there is no simple way to define what a "skin color" even means. An object's "color" is a complicated mix of the spectrum of the incident light and how that object absorbs and reflects that light. At present, skin colors are described using the Fitzpatrick scale, a qualitative method based on the light-absorption features of the skin, which determine both the skin's apparent color and its propensity to sunburn. It's important to also remember that skin is a living thing that changes thickness, color, and texture, depending on age and environment.
