Most likely your "purple" was once black, and is the negative; to verify, trace "purple" to ground, or touch the leads of an ohmmeter to purple and ground. You should get "0" ohms at the correct wire. This assumes a negative ground.

∙ 10y agoAC current (house wiring) typically does not have a negative- it has a hot, a neutral, and a ground. In the most basic AC wiring in the US, Black is hot, White is neutral, and Green (or bare) is ground. In DC circuits (in a car) there are two primary colors, Red for Positive, Black for Negative.
