Editing Spectral color (section)

==Extra-spectral colors==

Among some of the colors that are {{em|not}} spectral colors are:

* [[Grayscale]] (achromatic) colors, such as [[white]], [[grey|gray]], and [[black]].
* Any color obtained by mixing a gray-scale color and another real color (either spectral or not), such as [[pink]] (a mixture of a [[red]]dish color and white), or [[brown]] (a mixture of [[Orange (color)|orange]] and black or gray).
* [[Violet (color)|Violet]]-[[red]] colors, which include colors in the [[line of purples]] (such as [[magenta]] and [[Rose (color)|rose]]), and other variations of purple and red.
* [[Impossible color]]s, which cannot be seen under normal viewing of light, such as over-saturated colors or colors that are seemingly brighter than white.
* [[Metallic color]]s which reflect light by effect.
