You don't decide what the function of the wire is from the colour. Check out the pin-outs for connectors. But red is most commonly +5 VDC. Check this out: pinouts.ru/Slots/USB_pinout.shtml – Ashtray Sep 20 '13 at 6:53

Their is no standard on the colour the cables inside a USB cable are the only way to know what each does is to trace it from the connector where the standards apply
