If you have your hex value, and your just wondering what the value for the alpha would be, this snippet may help:

const alphaToHex = (alpha => {
  if (alpha > 1 || alpha < 0 || isNaN(alpha)) {
    throw new Error('The argument must be a number between 0 and 1');
  }
  return Math.ceil(255 * alpha).toString(16).toUpperCase();
})

console.log(alphaToHex(0.45));
