I have a chandelier that I bought in Europe, but the wires on the light are are brown, blue, and (green /yellow). Which colors connect to the black white and ground on the light from the fixture?

Remember that Europe uses 220V electricity circuits. The US is 120V.

White = Blue (Neutral)
Brown = Black (Hot)
Green w/Yellow = Green

You'll probably have to change the bulbs to 120V, but 220V bulbs powered by 120 will burn about half as bright.
