Convert Number to RGB Hex

[BananaFredSoft]

I have a program that deals with a brightness reading from a sensor. The brightness is 0 (black) to 100 (white). Is there a way I can convert this to a hex RGB color that I can use to, for example, set the background of a GUI as? Thanks.

I tried this and it didn't really work:

0x & Hex($array[$i], 2) & Hex($array[$i], 2) & Hex($array[$i], 2)
