You can use this generator to get nicely distributed color with the same saturation and lightness.

randomColorGenerator.js

// TIL that a `function *` in JavaScript makes a generator.
// Generators "yield" values and their execution is paused until next() is called.

function * randomColorGenerator(initialHue, saturation, lightness) {
  const phi = 0.618033988749895;
  let hue = initialHue;
  while(true) {
    yield `hsl(${Math.round(hue)}, ${saturation}, ${lightness})`;
    hue = (hue + phi * 360) % 360;
  }
}

let colorGenerator = randomColorGenerator(Math.random()*360, '80%', '50%');

console.log(generator.next().value);
console.log(generator.next().value);
console.log(generator.next().value);
