[JavaScript] I am trying to call one function to another function which calls an array.

I want to call 2nd Example to 1st Example, or to convert the colours of 2nd Example to 1st Example. But nothing works. See the 3rd silly and stupid example:

1) Example:

document.querySelector('input[type=color]').onchange = e => {
  const hexColor = e.srcElement.value
  document.body.style.background = telinkrinizeColor(hexColor)
}

function telinkrinizeColor (hexColor) {
  const [minLight, maxLight] = [32, 77]

  let [, red, green, blue] = /^#?([a-f\d]{2})([a-f\d]{2})([a-f\d]{2})$/i.exec(hexColor)
      .map(hex => parseInt(hex, 16) * 100 / 255)
  let maxColor = Math.max(red, green, blue)
  let minColor = Math.min(red, green, blue)
  let light = (minColor + maxColor) / 2

  light = Math.max(Math.min(light, maxLight), minLight)

  return `hsl(195, 34%, ${light}%)`
}

2) Example:

      let titlenames = ["original", "telinkrin"];
      let colours = ["#000", "#000009", "#0064A2", "#006575", "#ff99cc", "#DE6161", "#F0CA2A", "#FE4401", "#DFDFDF", "#00FF00"];

      function attachNewNode(target, colours, titlenames)
      {
          let length = colours.length;
          for (let i = 0; i < length; i++)
        {
          let node = document.createElement('div');
          node.className = 'palette';
          node.title = parseInt(i+1) + " – " + titlenames;
          node.style = `background-color: ${colours[i]}`;
          node.textContent = parseInt(i+1);

          target.appendChild(node);
        }
      }
      attachNewNode(document.getElementById("demo1"), colours, titlenames[0]);
      attachNewNode(document.getElementById("demo2"), colours, titlenames[1]);

3) Example:

      function getColours()
      {
        for (let i = 0; i < length; i++)
        {
          const hexColor = colours[i];
          colours = telinkrinizeColor(hexColor);
        }
        return getColours();
      }

attachNewNode(document.getElementById("demo1"), colours, titlenames[0]);
attachNewNode(document.getElementById("demo2"), getColours[colours], titlenames[1]);
