EDIT YOUR SHOTS
Treatment of the RAW file is just as important as the subject
The most natural colours result from going easy on the saturation or even pulling back on it. if you’re struggling with colour balance, it’s likely you have saturation dialled up too high.
in very flat light you may need to bump contrast a little in order to give hardness to edges. Adding contrast only at the black end of the histogram will help preserve tones elsewhere. Additionally, shadow detail can be lifted with the dynamic range tool to balance out the scene. Be sure to use layers to add exposure or more shadow detail if critical elements are lost in shade.
