Here I added a primary grade boosting reds in the highlights, greens in the mids and blues in the darks as well as more contrast and saturation. Then I applyed a secondary corection to both the skin and the lips to make them more natural. After that a added another primary to bring the whites back to white and black back to black.
Here I added another secondary corection to the branches in the back to get the color tint out of it.
This look would be saved out and applyed as a adjustment layer over already color corrected clips.
