Expand description
Operator for increasing the saturation (or chroma) of a color.
The trait’s functions are split into two groups of functions: relative and fixed/absolute.
The relative function, saturate
, scales the
saturation towards the maximum saturation value. This means that for a color
with 50% saturation, if saturate(0.5)
is applied to it, the color will
scale halfway to the maximum value of 100% resulting in a new saturation
value of 75%.
The fixed or absolute function,
saturate_fixed
, increases the saturation by an
amount that is independent of the current saturation of the color. So for a
color with 50% saturation, if saturate_fixed(0.5)
is applied to it, the
color will have 50% saturation added to its saturation value resulting in a
new value of 100%.
