colors wrong

I accidentally pressed something and now my desktop is black and my apps are in a black, blue and white theme pls help here are some pictures https://ibb.co/Nsy3p3y

Ok, idk what in the world is going on but suddenly yesterday or day before the entire metro thing looks weird.. it's like there is a gray skin cast over the area.. It started about the same time as the faulty nvidia driver update. the tiles got stuck flashing and then I restarted and that...
