If you are talking about the wiring of buildings/houses then blue would be a hot with ac current. If you mean wire in electronics then it would also "usually" be a positive but if there is any danger you should never assume. A tester could save you from having to buy a new component or your life.
AnswerThe European convention is that blue insulation indicates a neutral conductor, brown, black, or grey insulation indicates a line conductor, and a yellow/green striped conductor indicates an earth conductor.
