I'm writing a function to fade the background color of an element, and the function I've written works for hex values, but if I do element.style.backgroundColor in Firefox it returns the value as "rgb(r, g, b)" instead of the hex string. IE and Opera both return the hex string. Is it possible to force FF to return the hex value? I could just store the hex value in the code instead of grabbing it from the element, but I'd rather it be more flexible. I haven't been able to find anything online about making firefox cast to hex, and I don't really want to write a custom rgb to hex function.
