Let's take care of that with Curves!
Select the Adjustments icon and click Curves. The easiest way to take care of the white balance is by using the eyedropper tool and picking a black, grey or white part of the image. Since both are wearing white, I chose the white eyedropper and picked the lightest white in the image. I believe I chose a spot on the groom's collar.

Well, gosh, there is still that blue color cast on the bride's dress, so let's choose the selective color adjustment layer and lighten the blue and cyan. That's better!
Time to merge those layers!
I personally like to add a curves layer and then blend it as an overlay at 20 percent opacity, but that's just me.
Hmm, their skin looks a bit flushed, lets's take care of that.
This is why you don't use an action on every image, because they usually need to be treated individually. I just made a few adjustments in the Red selective color adjustment layer.
Their skin looks a lot better now. Let's put some pink back in the bride's lips.
Select the mask (the white part) and pick out a small paintbrush and paint her lips with the black paintbrush. This will put the red back.
