refers to the hue (color) component of the image. Note: hue 0 is blue, and hue wraps around. Hue is undefined at saturation 0 or at a value of 0 or 1.
refers to the saturation (colorfulness) component of the image. Note: a saturation value of 0 signifies pure grayscale. A saturation value of 1 signifies pure color. Saturation is undefined at a value of 0 or 1.
refers to the value (brightness) component of the image. A value of 0 signifies the color black. A value of 1 signifies the color white. Note: the spectrum exists at a value of 0.5 and saturation of 1.
