The actual color of something, such as naphthol red, sap green, or ultramarine, or the name we give a pigment or combination of pigments. What we generally, but less technically correct, call color.
When a tube of paint says 'hue' on it, for example cadmium red hue, it means that the color will be almost identical to genuine cadmium red, but the pigment is something different. A tube of paint labelled as a 'hue' may be a cheaper or blended version, it may be that the original color is no longer produced (such as Indian yellow), or it may be that the original was not lightfast (such as Hooker's Green).
