What is HSL Color Spaces?

The Hue, Saturation, Lightness (Luminance) system is like HSB/HSV. The main difference is that Brightness is a nonlinear parameter while Lightness is a linear one. Other applications sometimes use other models. Just Color Picker sets a value from 0 up to 255 for every parameter for HSL, and from 0 up to 240 for every parameter for HSL(Win).

HSL is similar to HSV. For some people, HSL better reflects the intuitive notion of "saturation" and "lightness" as two independent parameters, but for others its definition of saturation is wrong, as for example a very pastel, almost white color can be defined as fully saturated in HSL. It might be controversial, though, whether HSV or HSL is more suitable for use in human user interfaces.
