Hue

Hue is one of the main properties of a color, defined technically in the field of color science as "the degree to which a stimulus can be described as similar to or different from stimuli that are described as red, green, blue, and yellow," (the unique hues). The other main correlatives of color appearance are colorfulness, chroma, saturation, lightness, and brightness.

Usually, colors with the same hue are distinguished with adjectives referring to their lightness or colorfulness, such as with "light blue", "pastel blue", "vivid blue". Exceptions include brown, which is a dark orange.

In painting color theory, a hue refers to a pure color—one without tint or shade (added white or black). A hue is an element of the color wheel. Hues are first processed in the brain in areas in the extended V1 called V2 and V4.

Perception of hue

In Color vision in humans, the perception of hues is a result of cone cell responses within the retina. Our eyes contain three types of cone cells, each of which perceives light of a different wavelength. The brain interprets the combination of responses from these cells to perceive various hues.

Hue in color theory

In color theory, a hue is a pure pigment—one without tint or shade. A hue is an element of the color wheel. Hues include the primary colors red, yellow, and blue, and secondary colors green, orange, and violet. These, mixed in various combinations, can produce tertiary colors.

Hue in digital media

In digital media, hues can be created by adjusting the values of red, green, and blue (RGB) channels in a digital image. Each of these colors is created by "mixing" certain amounts of red, green, and blue light, and the intensity of each is represented by a number between 0 and 255.
