Where can I buy colored power cables?

I want to use color-coded cables for critical servers. Is it possible to purchase PC power cables in colors other than black and grey?

I've inherited a spaghetti-like mess of cabling in the server racks at my new company. There are dozens of servers each with dual power supplies, and there are two UPSs in each rack. Naturally each power supply is meant to be connected to a separate UPS. But since every power cable is black, and they're all routed together (and since they're all three times too long!) it's impossible to figure out which cable goes where, and I strongly suspect that some servers have both PSUs connected to the same UPS...
Ideally I'd like to buy a big box of blue power cables of various lengths, and another of yellow. Then I'd re-cable every last server, and it would be easy to visually confirm that they had redundant power.
(I'd also like to use red for critical devices without redundant power, and there are a few other special cases.)
I know I could color-code the ends of black cables with tape or something, and that's the fallback position, but really it'd be much nicer to have colored cables.
But I can't find a supplier anywhere! Power cables are the Model T of computing. You can have any shade you like provided it's black or gray.
