No. Green should always signify the ground wire.
More information is needed as to what device you are connecting to what power supply. The only two identifiable wires are the white and green. In North America the white colour is used for the circuit's neutral and the green is used for grounding of devices.
Black wire? You mean black insulation? If so, a black insulated wire would generally be a non-grounded conductor (preferably the hot line) and should not be connected to ground anywhere. However, someone may have improperly used a black wire for grounding, rather than green wire (or green/yel wire), or forgotten to wrap it with green tape.

Normally red or black is the hot wire and green is the ground. However someone may have used the green wire as the neutral wire which is normally white. Just connect the black wire from the light to the red wire and the white wire from the light to the green wire and see if it works. If not you have to pull the wires out of the ceiling box and see how they wired it.
the green wire its ground so you have black withe an ground

red wire, blue wire, green wire and the black wire.
the black wire is the hot wire
In typical American wiring the black wire on an outlet goes to the gold (copper) screw and the white wire goes to the silver screw. The ground wire goes to the green screw.
Black electrical wire is used for power in all circuits. Any circuit's black wire should be considered hot or live. Black wire is never used for a ground or neutral wire and should be used as the power feed for a switch or an outlet. A black wire is often used in a circuit as a switch leg, the connection that runs from the switch to the electrical load. Red electrical wire indicates the secondary live wires in a 220-volt circuit, used in some types of switch legs and in the interconnection between smoke detectors that are hard-wired into the power system. You can connect a red wire to another red wire or to a black wire.
There are probably dozens of black and white wires under the hood. It is a normal color for a ground wire. With out knowing where it or the green wire go, I can not answer.There are probably dozens of black and white wires under the hood. It is a normal color for a ground wire.
