<color> - CSS: Cascading Style Sheets
hsl colors the hsl color model defines a given color according to its hue, saturation, and lightness components.
... many designers find hsl more intuitive than rgb, since it allows hue, saturation, and lightness to each be adjusted independently.
... s (saturation) and l (lightness) are percentages.
... 100% saturation is completely saturated, while 0% is completely unsaturated (gray).

instead of red, green, and blue values, the hsl() function accepts hue, saturation, and lightness values, which are used to distinguish between the 16.7 million colors, but in a different way: hue: the base shade of the color.
... saturation: how saturated is the color?
... this takes a value from 0–100%, where 0 is no color (it will appear as a shade of grey), and 100% is full color saturation lightness: how light or bright is the color?
