Sometimes you might forget to set the white balance on your camera according to the actual shooting conditions. You get really yellow or blue colorings in the image. Sometimes it's just that time of day. They call it golden light. It's right after sun rise and right before sun set. It can be beautiful and warm and all glowing.
This is Nick and Lynn in Europe. Too cute. I wasn't there so don't know the time of day but I am guessing it was in the golden light time frame since it is outdoors. Their skin tone has a yellow cast, which isn't too bad. There is a filter if you prefer it to be more skin colored.
In Photoshop, Image>Adjustment>Photo Filter gives you a drop down menu. The first are golden colors which are useful when you have an image with a blue cast. But scroll down to the cooling filters and try one of the three. Just use your sense of correct to choose and manipulate the intensity of the filter with the slider.
Here is my adjusted image. Still cute!!! Which do you prefer?
