sat function
| Input type | Output type |
| color | float |
The sat function calculates the saturation of a color and returns it. The saturation ranges from 0 to 1. To construct a color from hue, saturation, and luminance values, use the hsl or hsla functions.
Examples:
sat(rgb(1, 0, 0)) ; 1.0 sat(rgb(0.5, 0.4, 0.3)) ; 0.2499... sat(hsl(1.5, 1, 0.5)) ; 1.0
