Don't spend a lot of money.  Buy these easy to use velcro cable tie wraps that allow you to use and reuse over and over again  Comes in multiple color pack (for that color coding you want to do).  Remember these aren't just for cables.  I've used them to hold shelves together for extra support!  These really stay stuck together!  I've chained a few together for a bigger project I needed help together.  A must have in any household.
