'color-enhancing' originates from the combination of 'color' and 'enhance', where 'color' refers to the property of an object that produces different sensations on the eye as a result of the way it reflects or emits light, and 'enhance' means to intensify or improve the quality of something.

'color-enhancing' evolved from the need to describe products or techniques that improve the appearance of colors, particularly in photography and cosmetics.

Initially, it meant 'to improve the appearance of colors', and this meaning has largely remained the same in modern usage.
