Abstract
A color coordination cone which permits a hair colorist to examine color mixtures before actual application. It is comprised of an internally illuminated cone-shaped base apparatus over which one or more transparent color cones comprised of twenty-four longitudinal color bands in eleven shades is placed. The color cones are rotated one over the other to examine the effect of mixing one color with another. In another embodiment of the invention, a colorless, transparent conical sheath with external tracks in radial planes corresponding to the edges of color cone shade levels is slid over the color cone. Elongated strips in various hues are slid between certain sets of adjacent tracks so that a particular hue on a strip will be positioned over a particular hue on the color cone and the results determined.
