The only designated colors in electrical wiring in North America are White as a neutral and Green as a ground wire. All other colors can be used as live wires. There are specific colors designated by the electrical code for phase wiring.
Answer for European Systems
The relevant regulations define all conductors, other than the protective (earth/ground) conductor, as 'live' conductors. In Europe, the line conductor has a nominal potential of 230 V with respect to the neutral conductor.
In Europe, the the three line conductors of a three-phase system are identified with brown, black, and grey insulation, respectively. For single-phase systems, brown is normally used. Neutral conductors are identified using blue insulation, and protective (earth/ground) conductors are identified using green/yellow stripedinsulation.

110v electrical wire color code for construction site?
black
How do you know which wire is hot on a cord with no color system?
The National Electrical Code requires that the neutral wire is to be designated as the "identified" conductor. Method differ, but look for ridges, lines, or writing on one of the wires.
Do you join brown electrical wire to red electrical wire and blue electrical wire to black electrical wire?
yes
Is a brown electrical wire live?
If you don't know different for sure, then you must treat ANY electrical wire as if it's live, regardless of what color it may be.
What is Grounding of an RV electrical system?
Connecting the ground wire to the metal chassis of the vehicle.

What does the black numbers on the electrical line mean?
On the wire itself? It'll have the type of wire as well as the size and maybe the manufacturer part number.
Rear speaker wire which is the positive in a impala ss 1994?
It will be the wire without the black line on it. Usualy the black line on a solid color will mean negative (-)
What is Grounding of an RV electrical system?
Connecting the ground wire to the metal chassis of the vehicle.
What color wire is connected to the silver screw in an incandescent fixture?
In most electrical devices the neutral wire is connected under the silver coloured screw.
How does a two-phase system differ from a three phase system?
A two-phase system is archaic and you are unlikely to find it in use anywhere these days, so it is mainly of historical interest. A two-phase, three-wire system, consists of two phase voltages, displaced from each other by 90 electrical degrees, and a phase voltage which is 1.414 x phase voltage.A three-phase system consists of three phase voltages which are displaced from each other by 120 electrical degrees. In the case of a three-phase, three-wire, system, the line voltages are numerically equal to the phase voltages; in the case of a three-phase, four-wire, system, the line voltages are 1.732 x phase voltage.
What color is the illumination wire on a 2002 Mistubishi Galant?
Green with a white line
How do 1 wire alternators work?
A one wire alternator has one wire that sends electricity to the battery and electrical system. They usually always have an internal regulator.
Which color wire is normally hot on a 120 volt system?
black
