Can you connect light fixture wires that are black white and ground to house wires that are red white and ground?

Yes, you can connect the light fixture wires to the house wires by matching the colors appropriately. The black wire from the fixture should connect to the red wire from the house, as both typically serve as "hot" wires. The white wire from the fixture should connect to the white wire from the house, which is the neutral. Finally, connect the ground wires (bare or green) together to ensure proper grounding.
