+
+Converts a HSL color tuple to RGB format.
+
+- Use the [HSL to RGB conversion formula](https://en.wikipedia.org/wiki/HSL_and_HSV#HSL_to_RGB) 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].
+
+```js
+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)];
+};
+```
+
+```js
+HSLToRGB(13, 100, 11); // [56.1, 12.155000000000006, 0]
