New light fixture will not turn off

Hello I recently bought a new light fixture for the kitchen and after installation the fixture will not turn off. The electrical box has a grounding wire, a white wire, a black wire and a red wire. The fixture has a grounding wire, white wires and black wires When taking down the old fixture I noticed that the black and red wires were connected so when putting up the new fixture I followed the same setup, however the light will not off once power is restored. When this happened I took it down and put the old one back up however now the old one will not turn off as well so Im completely stumped as to what has happened.
