Skin-Tone Analyzer Selects Right Color for Face Cosmetics
To determine the exact cosmetic color that will best blend with individual skin tones, a novel analyzing apparatus has just been introduced for beauty-shop use. A complicated system of lenses, prisms, and a polarizing screen is used to throw a tiny rainbow of light onto the skin of a customer. Analysis of the basic color tone of the skin is then made by noting which shade of the spectrum is most absorbed and which is most reflected.
