ChromaNails is a prototype that re-programs textures on photochromic nail polish to create high-resolution multi-colored on-body interfaces. By projecting different wavelengths of light, it can saturate and desaturate the photochromic particles to any partial saturation from transparent to fully colored. Using a photochromic nail polish mixture of cyan, magenta, and yellow (CMY), we create a multi-colored material with re-programmable capabilities. ChromaNails re-programs the photochromic CMY mixture using ultraviolet light and a modified RGB projector. The projection is controlled by an algorithm that utilizes the varying desaturation curves of the photochromic dyes.Â
