If you have a three digit hex for a color. For example #FFF and want to convert it to a 6 digit number here’s a simple way:
// Expects 3 digit hex, like '#FFF';
function uniformColorHex(hex) {
let newHex = "#" +
hex.charAt(1) +
hex.charAt(1) +
hex.charAt(2) +
hex.charAt(2) +
hex.charAt(3) +
hex.charAt(3);
console.log(hex + " => " + newHex);
return newHex;
}
