lchToHpluv static method
HSLuv values are ranging in 0;360
, 0;100
and 0;100
.
@param tuple An array containing the color's LCH values.
@return An array containing the resulting color's HSL coordinates in HPLuv (pastel variant) color space.
Implementation

}
if (L < 0.00000001) {
return [H, 0, 0];
}
double max = maxSafeChromaForL(L);
double S = C / max * 100;
return [H, S, L];
