What does blue wire mean?
“Blue and yellow wires are sometimes used as hot wires,” Dawson says. Specifically, blue and yellow electrical wires are often used as “traveler wires” for transferring power between three- or four-way switches. Yellow is more commonly used as a switch leg instead of a traveler wire in these applications.
What do different color electrical wires mean?
Electrical wiring comes in one of several colors: Black Wires – when you see a black wire, always assume it’s live. Blue Wires – always assume they are live if you have power. Blue wires are also fed through a conduit, usually bringing power to three or four-way switches. Green Wires – green wires are grounding wires.

How do I know which wire is positive and which is negative without a multimeter?
If there’s a strong current flowing and you have a suitable magnet, you might be able to tell by which way the wire or the magnet moves when you bring the two close. A compass needle will swing one way or another in the presence of a current, too. Current flows from positive to negative.
