Color grade
When I do film work I always prefer shooting in log profiles. A log image is usually a very flat image meaning less contrast and saturation than you would expect from a normal sRGB or Rec.709 image. The reason you would use a log profile when capturing the footage is to expand the dynamic range (number of exposure stops between black and white). A log profile requires a lot more work in post but usually yields a better result and gives more control at the color grading stage.

There are different approaches to get the image back to a "natural" stage. I tend to use a color checker card at the scene. Another important thing is to have proper white balance set at the moment of capture, especially when working with compressed formats opposed to RAW format.

Creative grade
Pushing the image even further, more color separation and compression.

My preferred tool for color grading is DaVinci Resolve Studio.
