Why is it red to shoot pink clothes indoors with Canon 550D suit? This is a studio. Do you have a flash? Which key should I adjust?

Adjust the white balance, that is, the button with WB logo. Generally speaking, pink is red, which means that the white balance has a high color temperature. Try to adjust the white balance according to the daylight file. Generally, the sunlight is 5200K and the cloudy shadow is 6000 K. If there is enough light when shooting, the picture color will be red when the color temperature is too high and blue when the color temperature is too low. Of course it depends on the light at that time. Try every gear. Moreover, the teacher said that the photos found by adjusting the white balance that does not conform to the current light sometimes have different aesthetic feelings, so try them all ~ ~ ~
