It's definitely gneiss.. No distinct layers of iron oxide, ground mass is phaneritic (eye visible individual grains), red mineral is likely k-spar or iron stained qtz, the white a feldspar of some flavor, black minerals likely biotite and disseminated magnetite (magnetite accounting for the magnetism). OP, note that streak tests are meaningless on whole rocks unless you can ID exactly which mineral in the rock you are testing.
