How can I fix my light in the Kitchen?

Hello! I just came one evening into my kitchen and the light was not working. I checked if the rest of the things like sockets, washing machine and freezer had power and everything was fine. I have changed the light swichter and I thought by changing this it would work again. Nothing happened I still without kitchen light. So I decided to buy a new lamp which i tried to install. When i was removing the old lamp only 3 cables came out of the celing: 2 black and 1 red. One in green was connected with a screw to the lamp only and the other cable (green with yellow) which was connected was randomly to screwed to the lamp too. I connected the cables like they were connected to the previous lamp but it still not work and I don't know what could be the problem. I would really appreciated any thoughts or ideas to fix this.
Thanks
