Some examples include: Cobalt chloride is pink or blue depending on the state of hydration (blue dry, pink with water) so it is used as a moisture indicator in silica gel. Zinc oxide is white, but at higher temperatures becomes yellow, returning to white as it cools.
Additive color or additive mixing is a property of a color model that predicts the appearance of colors made by coincident component lights, i.e. the perceived color can be predicted by summing the numeric representations of the component colors. [1]
E.g. a saturated pink would be fully defined by its visual similarity to red, blue, black and white. [2] Colors in the NCS are defined by three values, expressed in percentages, specifying the degree of blackness (s, = relative visual similarity to the black elementary color), chromaticness (c, = relative visual similarity to the "strongest ...
