Kind of old, but it works. 
Description: Darkens/brightens the hex code you provide.
Syntax: convertHex(string, condition);
var validHex = "0123456789ABCDEF", x = 0;
function convertHex(a, b) {
var newHex = "", i = 0, x = 0;
while(i < a.length) {
var returnItem = validHex.charAt(validHex.indexOf(a.charAt(i ++)) + b);
newHex += returnItem ? returnItem : 0 + b < 0 ? 0 : "F";
}
return newHex;
}
Example: convertHex("0099CC", x + 2);
The first parameter of the function takes the hexcode as a string. The second part uses the variable x to represent the color code as it's value is subtracted or added by any number. In this case we are increasing it's brightness by "2". The result will be: 22BBEE
