HUE
I tend to avoid making adjustments to the Hue sliders because doing so will change the shade of the color, taking you too far from the look of the preset.
SATURATION
The saturation sliders allow you to adjust the intensity of each color. Most of the time a simple desaturation of a specific color will make your image look better.
I tend to always decrease the yellow saturation slider for indoor images and decrease the green saturation slider for outdoor images. If you’re trying to figure out what color you will need to decrease, look for a color cast in your image then pull that color saturation slider down to fix it.
For example, I have terrible yellow-orange hardwood floors and when I’m shooting in my living room during the day the natural light from the windows reflects off the floors creating an orange color cast on my subject. The easiest way for me to fix the color cast from the floor is to pull down the orange or yellow saturation slider until I feel the skin tones look correct.
Another example would be if you’re shooting outside in the grass or in the woods, noticing a green color cast on your subject’s skin. Pulling the green saturation slider down just enough to take the color off their skin will make a huge difference.

LUMINANCE
The Luminance panel will allow you to adjust how bright or dark a color is. I will only adjust this if I feel like a color is too distracting, decreasing the slider to make it darker and less noticeable.
Keep in mind that the best ways to avoid needing to make color adjustments in the HSL panel is to place your subject in good light and to avoid shooting in situations that reflect a color cast. For natural light photographers, sometimes that can be a bit more challenging. If we can avoid color casts, it will make your editing workflow much faster.
When I’m outdoors, I try to find a natural reflector to not only bounce good light in front of my subjects but to also deflect any color cast that might affect my subject’s skin tone. I use a neutral colored building, neutral colored concrete sidewalks, white gravel, etc.
If I’m indoors and plan to stand pretty close to my subjects while shooting, I wear a neutral colored shirt like white, gray, or black and avoid orange, yellow, or bright green colored clothing.
