All my power cables and speaker cables are black. I apologize, however, for the fact that my 5- to 10-foot balanced patch cables are all red. My 5-foot inserts are blue. I never have any problem figuring out which cable to grab, even in the dark. BTW, if it'll make you feel better, my unbalanced patch cables are black. All of this stuff resides behind the rack at FOH, and any excess is coiled inside the rack. It's a beautiful thing. With the color-coded ends, it takes me less than 60 seconds to patch the rack to the board. All the amp inputs and outputs are on panels on the back of the amp racks, color coded as well. No, I'm not a pro, I'm just anal. And even as such, the utility of quick cable identification outweighs my fear of apparent dorkiness.
