How to adjust the settings 

Depending on your photo you need to adjust the whitebalance. The tempature make your photo warm (blue) or cold (yellow). So if you find the presets either to cold or warm please change the settings. The colour tone makes your photo more purple or green. Use it if your photo looks to green or purple.

What if my skin looks to orange the sky is too blue?

Adjust one specific color

For skintoens and warm colours in your picture

Go to the color section in Lightroom and change the settings for orange. If your skintone is to colourful make the saturation lower. If your skin looks to red change the hue.

These colours are made for the blue colours in your picture. As mentioned above change these settings to change the specific color in your picture.
