scale-color() produces incorrect colors #2903
Description
LibSass's scale-color() function output doesn't match that of Dart Sass or Ruby Sass in a number of cases:
scale-color(turquoise, $saturation: 24%, $lightness: -48%)
should be #10867a, is actually #0d897c
scale-color(plum, $saturation: 67%)
should be #f489f4, is actually #e895e8
scale-color(plum, $saturation: 100%)
should be #ff7eff, is actually #ed90ed
There are likely other cases that are invalid as well.
