Hue
Hue is one of the main properties of a color.
It is defined as “the degree to which a stimulus is similar to, or different from, stimuli that are red, green, blue, and yellow” (the unique hues).
The other main aspects of color appearance are colorfulness, chroma, saturation, lightness, and brightness.
Usually, colors with the same hue are distinguished with adjectives referring to their lightness and/or chroma, such as with "light blue", "pastel blue", "vivid blue".
