Method 1

This script will help us convert colours from heximal to decimal values.

function HextoDec(h) {  
	var dec = parseInt(h, 16); // 16 to 10 base 
	// 16777215 
	return dec 
}

// HexToDec("FFFFFF") = 0

function DectoHex(d) {

//    convert number to 32-bit String, number converts the object to a number 
    var hex = Number(d).toString(16).toUpperCase().padStart(2, '0');
  return hex;
}
// DecToHex(16)= 10
