HSLToRGB

Converts a HSL color tuple to RGB format.

• Use the HSL to RGB conversion formula to convert to the appropriate format.
• The range of the input parameters is H: [0, 360], S: [0, 100], L: [0, 100].
• The range of all output values is [0, 255].

const HSLToRGB = (h, s, l) => {
  s /= 100;
  l /= 100;
  const k = n => (n + h / 30) % 12;
  const a = s * Math.min(l, 1 - l);
  const f = n =>
    l - a * Math.max(-1, Math.min(k(n) - 3, Math.min(9 - k(n), 1)));
  return [255 * f(0), 255 * f(8), 255 * f(4)];
};

HSLToRGB(13, 100, 11); // [56.1, 12.155, 0]
