MacBook Air Display Color Temperature Changes After Logging In

This is normal.

When macOS is booting it will access your settings and see if you have specified the color temperature. Or enabled Night Shift.

If you have enabled FileVault this change will happen after you are logged in.

I think you need to put Color Temperature on Less Warm instead of in the center. And/Or turn off the Night Shift option.

I have the same problem. It changes to a warmer color temp everytime my computer goes to sleep and I have to log in again. I have Night Shift off permanently and color temp is set all the way to the left to Less Warm.

What I do is open Display settings, and navigate to Night Shift. I quickly turn it on manually and then disable it again. That seems to reset the color temp so that my whites are white and blues are blue.

This is a pretty big issue if you want to edit photos or videos on your macbook, like many do...

I had the same issue Idk if you guys are still having the problem two years later, but for others who are try turning off True Tone under Display. If the problem is still happening after that I have no clue.
