What does the term "hue" refer to in color theory?

In color theory, the term "hue" specifically refers to the name of a color, which is determined by its wavelength of light. When we think of "hue," we are considering the basic colors that we can identify and name, such as red, blue, yellow, and so on. These colors correspond to specific wavelengths of light within the visible spectrum.

Hue is one of the three main components of color, alongside saturation and value. Saturation refers to the intensity or purity of a color, while value denotes its brightness or darkness. Therefore, knowing that hue pertains directly to the color's identity based on its light wavelength helps clarify its role in the broader context of color theory.
