So you have some good replies here already. The color correction of this image is a standard technique you want to master to successfully edit your images in the future. It is a simple white balance issue. You can either use just the white balance module alone and turn off the color calibration module or set the white balance module to camera reference (the default) and use the color calibration module to calculate the white balance from a selected region of the image.
I also sometimes “fine tune” the color using the rgb curves module. To add a little red just raise the centre of the red curve or to reduce red just lower it a little from the centre. The same adjustments apply for the green and blue channels by adjusting their curves. With your image the white balance calculated from a selected region of the image was a little cold looking so I add a touch of red and yellow using the rgb curve module.
