Definition - What does Hue mean?
Hue, in the context of color and graphics, refers to the attribute of a visible light due to which it is differentiated from or similar to the primary colors: red, green and blue. The term is also used to refer to colors that have no added tint or shade.
Techopedia explains Hue
The hue of a color pixel is one of the very fundamental concepts in digital image processing. Along with saturation and brightness (brilliance), hue makes up the three basic aspects of any color. A color is far more complex than its name because of the variety of shades available in each color. In digital image processing, pixels with slightly different colors have slightly different RGB code (value). This is because of slightly different dominant wavelengths of that color which constitute the hue. A pure hue is completely saturated, meaning no white light is added.
