Increases or decreases one or more properties of $color by fixed amounts.
Adds the value passed for each keyword argument to the corresponding property
of the color, and returns the adjusted color. It’s an error to specify an RGB
property ($red, $green, and/or $blue) at the same time as an HSL
property ($hue, $saturation, and/or $lightness), or either of those at
the same time as an HWB property ($hue, $whiteness, and/or
$blackness).
All optional arguments must be numbers. The $red, $green, and $blue
arguments must be unitless and between -255 and 255 (inclusive). The
$hue argument must have either the unit deg or no unit. The $saturation,
$lightness, $whiteness, and $blackness arguments must be between -100%
and 100% (inclusive), and may not be unitless. The $alpha argument must be
unitless and between -1 and 1 (inclusive).

The hue is a number between 0deg and 360deg (inclusive). The whiteness and
blackness are numbers between 0% and 100% (inclusive). The hue may be

channel can be specified as either a unitless number between 0 and 1

⚠️ Heads up!
Sass’s special parsing rules for slash-separated values make it
