How to connect a light from ceiling. Wires green, brown and blue?

OK not the usual colors and these are coming from ceiling I hope so the light fixture wires should be green or bare copper or none, a white and a black (I hope)  so greens or bare copper to green as ground wire, cap off,  brown should go to white as neutral and cap off, and blue to black as hot and cap off. If you try and the breaker trips, then reverse the brown and blue to black and white respectively but I'm positive youll be alrightv the first time or let me know
