How to wire replacement light fixture

The new light fixture has black, white, and copper wires. How do you wire to existing yellow, white, and dark green wiring shown in photo? Thanks in advance.

Where are you located? If you are in North America I would test the wires to find what each does since they are not the standard black (hot), white (neutral) and green (ground).

use a meter check like PD suggested. But most likely yellow is hot white is neutral and the green is ground. Since it's only a light it won't make a big difference. But, don't take my word for it. That green wire with insulation bothers me. How the heck did that pass inspection?

Insulated green ground and yellow wire suggest a conduit system.

Good point. Never thought of that.

Green should still be checked with a meter to be sure it is not a rogue color and live!

Thanks for all comments. I will check the wires. I think all of the units around mine have this same wiring. This is a large planned development, so I would think there were strict inspections. The light I pulled off had only 3 wires too, one was a copper ground wire. So it would make sense that the yellow is hot and the white is neutral.
