เฉดสี (Hue)

Hue is the most fundamental property of color and corresponds to the dominant wavelength of light. It is what most people mean when they say 'color' in everyday language. On the color wheel, hue is represented as an angle from 0 to 360 degrees, where 0 is red, 120 is green, and 240 is blue. In the HSL and HSV color models, hue is the first component. Hue is independent of lightness and saturation; for example, a dark navy and a light sky blue share the same hue but differ in value and saturation.
