I’m pretty sure we can use 24 gauge wire for for hooking up a potentiometer. Do color requirements not apply to 5v sensor wire, or do I need to get some red black and white 24 AWG wire?
R46:
<R46> All active Power Distribution Board branch circuit wiring with a constant polarity (i.e., except for relay module, speed controller, or sensor outputs) shall be color-coded as follows:
A. Use red, white, brown, or black with stripe wire for +24 Vdc, +12 Vdc and +5 Vdc connections.
B. Use black or blue wire for common (-) connections.
So for a pot, you will have common (black or blue), +VDC (red, white, brown, black w/stripe), and wiper (anything you please - but avoiding the same colors you used elsewhere is a good practice. Usually I use yellow or white for signal).
• Connect the wiper to the input pin – Top row.
• Connect the other two pins to +5 and ground – Middle and bottom rows.
There is a thread about this.

If that helps that is.
Sparrow,
Although there is no strict rule governing sensor color code, standard practice would make that recommendation. R46 above relates to power distribution as Abwehr pointed out and those colors may be used. A PWM cable makes a perfect connection medium for your application and will maintain a color code that both you and others can easily identify. Red for positive voltage, black for common and white for signal or in your case, pot wiper.
Gauging can be light for sensors and signal devices. We’ve always followed the practice of using red for V+, black for GND, and white as a signal color.
PWMs are perfect for this as they give you the connector on the other end if you are connecting the device directly to an input.
