The contractor installed a bunch of #14 THHN purple conductors as part of a control system installation. there is a Indicator out in the field to show that a pump is running. he used a purple wire for the grounded conductor (neutral wire) seems to me this conductor is required to to be white or gray per 600.6. the contractor is telling me to jump in a lake! Am i getting this wrong or is there an exception somewhere that allows this?

perhaps you meant 200.6. if so, you may well be correct.

the lake is probably getting pretty cold this time of year. did you enjoy your bath?
 
If the control wiring is low voltage and limited power, none of the color requirements of the NEC may apply to it. Just telling us that it is control wiring is not enough information.
 
I do not think it necessarily does, but have you always seen white used for the grounded conductor on doorbells and thermostats? Or had an inspector call you on that?
And I have never seen the grounded conductor (metal sheath) on a gas pilot thermostat painted white.
Jus' sayin'. :)

There are different rules for the grounded conductor identification when using cable. The OP said this was #14 THHN.
