ABSTRACT:
A color scale palette has color sample rods tinted all along their lengths from a stem in a frame to the other end projecting from the frame. The frame has a window for exposing a portion of the color sample rods and, for example, a color key, and studs cooperative with a bore through the stem end of each color sample rod for snapping it into the frame. The bore is preferably a funnel-shaped for shadow-free as well as juxtaposed color comparisons.
