There is a hypothesis that the first days after birth the child most of the time sees the ceiling of white, on which white balance is displayed.
YYYYYYYYYYYYYYYYYYYYYYYYYYY If the ceiling was not white, the balance of white would be broken for life. How to calibrate the child again?
zzz: In the system menu, drop the settings to factory settings. But probably everything else will have to be calibrated.
XXX: Remove the settings. But then he will be writing in the plank again.
