What is the reason for the discoloration of Canon SLR studio photos?

This must be a color temperature problem, and the automatic white balance of the camera cannot be adjusted correctly. Solution: 1, set different white balance values, and find the setting that can display colors correctly. 2. After using the gray card, the accurate color temperature can be adjusted according to the gray card. 3. Shoot it into RAW file format in the early stage, and adjust the color temperature lossless in the later stage to achieve the correct effect of color restoration.
