According to Crayola , COLOR ( American English ), or COLOUR ( Commonwealth English ) is the aspect of things that is caused by differing qualities of light being reflected or emitted by them .
HUE , or spectral colour , is the traditional colour name given to a specific wavelength of light in the light spectrum , such as red , yellow , or blue . When you refer to hue , you are referring to pure colour , or the visible spectrum of basic colours that can be seen in a rainbow .
The Merriam-Webster dictionary further defines colour as the quality of any object in terms of its emitted or reflected light , described visually in terms of hue , saturation , and value .
SATURATION , also known as the intensity , or chroma , refers to the relative purity of the hue - the absence of black or white . Highly saturated colours appear rich and vibrant while desaturated colours appear muted or greyed-out .
