The hue

between 0 and 360. Values outside of this converted as hue % 360
to
be fit into the standard angle range.
The saturation
is given as a percentage between 0 and 100 (inclusive).
The luminance
is given as a percentage between 0 and 100 (inclusive).
Implementation
const HslColor(num this.h, num this.s, num this.l);
