Implementation

HSVColor hslToHsv(HSLColor color) {
  double s = 0.0;
  double v = 0.0;

  v = color.lightness + color.saturation * (color.lightness < 0.5 ? color.lightness : 1 - color.lightness);
  if (v != 0) s = 2 - 2 * color.lightness / v;

  return HSVColor.fromAHSV(
    color.alpha,
    color.hue,
    s.clamp(0.0, 1.0),
    v.clamp(0.0, 1.0),
  );
