Grey card is useful provided there is a single color temperature in the scene. Flash augmented daylight shots and tungsten augmented strobe or flash light will need gelling the strobe to get one effective color temperature. It i possible in post to select the subject and place on another layer and adkust white balance to match the backrground or the opposite, which works on subjects which are easily selected by being fully in front of the background or fully behind it. Mixing light can be creative depending on the audience but anything that is intended to be accurate or editorial needs to have the light of the same temperature.
