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.
Yes, the green conductor is the colour of the ground wire in an extension cord. The black wire is dedicated to be the "hot" and the white conductor is the neutral.
GREEN
Yes, the red wire is a positive wire (+) and the black wire is a negative wire (-) :D
the black wire is the hot wire
In typical American wiring the black wire on an outlet goes to the gold (copper) screw and the white wire goes to the silver screw. The ground wire goes to the green screw.
Because the colour of a "negative wire casing" is black, hence the reason why negative numbers were written in this colour :)
According to color code, it is the speaker negative wire.
In a DC circuit Red is positive and Black is negative. In AC systems White is neutral and Ground is green or green-yellow stripe.

More information is needed as to what device you are connecting to what power supply. The only two identifiable wires are the white and green. In North America the white colour is used for the circuit's neutral and the green is used for grounding of devices.
The red wire is the positive wire. The black wire is the ground wire. The green and yellow wires are the speaker wires. The white wire is the auxiliary wire.
Blue, Green, Red, Black, White or Yellow. Not sure which one.

your an idiot. what color is the negative wire for everything. BLACK!!!AnswerI think it is the Red one. Red is the color code for the positive terminal (also for your battery tender). Black or green indicates the negative terminal..
The red wire is the positive wire. The black wire is the ground wire. The green and yellow wires are the speaker wires. The white wire is the auxiliary wire.
GREEN
Yes, in North America the ground wire is always identified as a green colour conductor.
