A quick script using a bitwise operator to convert a color hex string into RGB.

ColorHexToRGB.js

const convertHexToRGB = (hex) => {
  hex = hex[0] === '#' ? hex.substr(1) : hex;
  const rgb = parseInt(hex, 16);
  return {
    Red: (rgb >> 16) & 0xFF,
    Green: (rgb >> 8) & 0xFF,
    Blue: rgb & 0xFF
  };
};
