Average 2 hex colors together in javascript

Question

Alright thought I would throw this one out there for the crowd to think over.

Given a function (written in javascript) that expects two strings

Answer 1

Here is the function

function avgColor(color1, color2) {
  //separate each color alone (red, green, blue) from the first parameter (color1) 
  //then convert to decimal
  let color1Decimal = {
    red: parseInt(color1.slice(0, 2), 16),
    green: parseInt(color1.slice(2, 4), 16),
    blue: parseInt(color1.slice(4, 6), 16)
  }
  //separate each color alone (red, green, blue) from the second parameter (color2) 
  //then convert to decimal
  let color2Decimal = {
    red: parseInt(color2.slice(0, 2), 16),
    green: parseInt(color2.slice(2, 4), 16),
    blue: parseInt(color2.slice(4, 6), 16),
  }
  // calculate the average of each color (red, green, blue) from each parameter (color1,color2) 
  let color3Decimal = {
    red: Math.ceil((color1Decimal.red + color2Decimal.red) / 2),
    green: Math.ceil((color1Decimal.green + color2Decimal.green) / 2),
    blue: Math.ceil((color1Decimal.blue + color2Decimal.blue) / 2)
  }
  //convert the result to hexadecimal and don't forget if the result is one character
  //then convert it to uppercase
  let color3Hex = {
    red: color3Decimal.red.toString(16).padStart(2, '0').toUpperCase(),
    green: color3Decimal.green.toString(16).padStart(2, '0').toUpperCase(),
    blue: color3Decimal.blue.toString(16).padStart(2, '0').toUpperCase()
  }
  //put the colors (red, green, blue) together to have the output
  let color3 = color3Hex.red + color3Hex.green + color3Hex.blue
  return color3
}
console.log(avgColor("FF33CC", "3300FF"))
// avgColor("FF33CC", "3300FF") => "991AE6"

console.log(avgColor("991AE6", "FF0000"))
// avgColor("991AE6", "FF0000") => "CC0D73"

console.log(avgColor("CC0D73", "0000FF"))
// avgColor("CC0D73", "0000FF") => "6607B9"
