I don't think you should decide anything on the colours, they could be connected just about any fri*ing way depending on what mood the manufacturer was on. Measure them, or if you can slide the sleeve off the remaining connector, look inside it.
When I needed one, I could have made it up myself, but just decided to save myself the trouble of soldering and hunting for suitable raw cable, and bought one off eBay:

Arrived quickly, and the quality is just fine.
