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.
