How to understand the three primary colors and how the complementary colors between the three primary colors complement each other?

One of the photos taken by the SLR camera is too heavy. Maybe you set the wrong color mode. You may have set the high saturation mode to make some colors overflow. The natural scenery we see is a composite color, and the photos taken by a SLR camera are "one color is too heavy" rather than a simple single color, so it is difficult for us to determine which color is the "complementary color" of "one color is too heavy", so it is almost impossible to adjust it. Remember, you should pay attention to setting the "color saturation" mode correctly before the next shooting to reduce the loss.
