Color
/ Adjust / HSV, HSL
The HSV model is defined by the parameters hue, saturation and value. In the HSL model, the term lightness is used instead of value. The advantage of these models is the intuitive way of
mixing colours. When manipulating a colour, the appropriate hue is selected in the first stage, followed by saturation and lightness in the second stage. The colour hue does not change when manipulating saturation
and lightness, which is hardly possible to achieve with RGB or CMYK models.
