Hexadecimal values have a lot more use than just the hardware/debugging related information I mentioned in my [Counting in Hexadecimal](http://blog.kirupa.com/?p=69) post. If you do any type of design, you are probably familiar with the hex codes used for describing a color. The most common way for describing colors has been RGB where a pair of values specify the level of Red, Green, and Blue. For example, a color such as pure white would be #FFFFFF.
