It's an easy effect to achieve, but if you ask me, she's lit with white light. Her hair is most definitely auburn, and her cheeks from makeup seem a bit orange too. I don't see a lot of orange in that original image though. The practicals will naturally have a bit more hue.
But if you want an orange or brownish tone to your image, capture it in camera! A simple filter will do the trick. If you're on Tungsten film throw in an 85 or two. Tobacco filters and chocolate filters are worth eyeballing also. If you want to control the orange hues on set, then a simple choice of gel such as CTO or CTS would suffice to create these colors.
Of course, test everything first. Then you can choose the look that best suits the film.
Here's an image from a film my buddy shot for me, you can see the orange on the skin tones very clearly. He utilized the 85 for this.
