It will have 2 black or brown wires. Look very closely at the wires coming from the light. One of the wires will have ridges on it or may have a white line or some other method of identification. That wire is the neutral wire and connects to the white wire in the ceiling box. The smooth wire is the hot wire and connects to the black wire in the ceiling box.
In USA an AC light fixture isn't polarized, so color-matching wires is not required.
Black is hot and white is neutral.
The short answer is wire color to color. black to black, white to white, green or bare to green of bare.
Black to Black - Black from the ceiling is a hot wire and should be switched Red to Blue - Red wire is another hot wire and should also be switched White to White - White from the ceiling is the neutral and should not be switched. Your wall should have two switches, one will control the red wire, one will control the black wire. If you wire your fan as above, one switch will turn the fan on, the other will turn the light of the fan on.

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.

This question isn't clear.

because it doesnt reflect light. actually black is black because it reflects minimal light a good way to say this is that the only thing which doesnt reflect light is a black hole which absorbs all forms of light due to a high amount of gravity but a black hole is technically not black because it doesnt reflect any light what so ever marvin the martian is a black mouthless martian and marvin the martian is a woman

If there are two black wires, it's possible that it was wired for a ceiling fan and that one of the wires is for the fan part while the other is for the light part. If so, one of the black wires may be switched while the other is always "on." Normally black is "hot" and white is "neutral" (NOT ground... ground is usually green).

If both wires are black, the one that connects to your white wire is the one that should have little writing on it. Black to the plain black wire, white to the wire with writing.
Ground
Just remove the old light and install the new pull chain light connecting the black wire to the copper screw and the white wire to the silver screw. There is no connection for the ground wire. Just shove it back into the ceiling box.
