Java Color Integer To RGB String In JavaScript

I'm trying to use some Java Color int values from a database in Javascript. What's the correct way to convert the Java color int (like -2147473665) to an RGB string (like '#ffff00'

Solution 1:

You need to handle signed integers. See How to convert decimal to hex in JavaScript?

console.log(getHexColor(-16731137)); // light blue
console.log(getHexColor(-1218518)); // orange

function getHexColor(number){
    return "#"+((number)>>>0).toString(16).slice(-6);
}
