Wire Color Woes

[Jon Stratis]

That is certainly legal. I would strongly recommend, however, maintaining some sort of standard on the outputs of your relays and speed controllers. Every relay and speed controller has a labeled positive and negative, even though the polarity may change. Likewise, most of the motors we use have indicated positive and negative terminals. The combination of the two allows for easy wiring of motors that have to work together.

For example, if you have 2 CIM's going into a Tough Box, hooking the red's to the positive output of two Jaguars, and the blacks to the negative, you know that setting the Jaguars to the same value will spin the CIM motors the same - there's no trial and error where you don't know which way each motor will spin.

By maintaining some standard (for example, purple is always attached to the negative output from a speed controller, and teal always to the positive), you can possibly save your team some headaches if you burn out a motor and need to do a fast replacement between matches.
