Abstract: A device includes a freely manipulable color-mapping wand. The wand includes at least one color detector for measuring an intensity of light within at least one spectral range that is incident from a region of a surface. A navigation sensor produces a signal that is interpretable to yield a position of at least a portion of the color-mapping wand.

Abstract: A makeup practice book includes a three-dimensional model mounted on a bound page of the book, the model including a surface to which a makeup substance may be applied. At least one compartment for holding a makeup substance that may be applied to the surface is provided on a bound page of the book. Each page of one or more bound pages adjacent to the page on which the model is mounted includes a cutout section that is aligned to the model, such that the surface is accessible via the cutout section when the book is open to a page of the adjacent bound pages.
