Color phase composition of color image

Quick answer：

Color images are composed of different hues, which are determined by the color phase. The color phase refers to the position of a color on the color wheel, and it is one of the three main attributes of color, along with saturation and brightness. In digital imaging, the hue is represented by the HSL (Hue, Saturation, Lightness) or HSV (Hue, Saturation, Value) color model, where the hue value defines the specific color. Understanding the color phase is crucial for various applications, such as image processing and color theory.
