Question: MacBook Pro Touch - Screen Color Changes

Hi everyone,


So Im having an unusual issue on my 15" MBP with Touch Bar.

Every so often the screen will change its hue, it normally either goes warmer, or sometimes has a purple tinge.


When it happens its kind of noticeable. I either have to change my display profile, or restart the system to get it back to normal.


I've been doing a little testing, and it also seems to happen when I push processor with

yes > /dev/null


I will continue testing and see what I find, but i'm just wondering if anyone else is having similar issues.

I also experience video glitches, like flickers when watching online, or local videos.

MacBook Pro TouchBar and Touch ID, macOS High Sierra (10.13.3)

So my MBP went into the service center and had both a screen replacement and logic board replacement..


Everything was working for around 4 days, then the problem came back, screen hue suddenly drops from bright white to a dull pink.

For me it happens very infrequently, and I think it has only ever happened within a few minutes of coming out of sleep mode.


Use case: Put laptop to sleep, put in Timbuk2 bag, go to work, take out laptop, open up screen and it comes out of sleep...wait a few minutes and observe unexpected color temperature occurring that settles out within a minute or so.


As my MBP is still under warranty, I am thinking of bringing it in....but I have been wondering if it might be a bug with High Sierra 10.13.5 Beta (17F70a)


Automatically adjust brightness is OFF (no check in check box)
Night Shift schedule is OFF

Color temperature is all the way to the left (Less warm)


I have found something interesting. If I depress the mouse on the color temperature slider...without moving it...the effect that is created is very similar to what I observe sometimes. The screen gets pinkish and then settles down to the expected color temperature. That's probably just a coincidence, but might help someone understand the phenomenon better.

Hey Greg, I would be interested to know how you get on with going to the repair center. Ive had both the logic board and screen replaced but still have the same issue. So I'm also thinking it could also be a bug in High Sierra.


I calibrated my display a little cooler than the native white point, around 7000. When the pink flash happens the screen seems to actually go a little warmer. Its only when I drag the slider on the color temperature that it seems to normalize back to the cooler color I set. Even though this happen, the screen does seem to creep to the warmer side of things after some time.


I'm thinking that there may be some issue with the way the system reacts to ambient temperature, even it's switched off.


Maybe you could set a cooler temp on your screen and see if you notice something similar.

I just had my display replaced, and I still have the exact same issue, so this must be an operating system issue.. Considering taking the machine back for a refund. Its really disappointing that apple products are now of such poor quality, but I guess its all about making a profit.

I have the same issue with my MacBook Pro 13"; 2017; Touch Bar; 500gb; 3,1 Ghz; 16gb ram

Intel HD


Night-shift is OFF
Automatic light adjustment is OFF


One of my active corners is "show desktop" and once I hit that it went back to normal

and then it comes back randomly


Also, even though automatic ligh adjustment is turned off, IT DOES ADJUST THE BRIGHTNESS ANYWAY!


please help, this is annoying.

Same thing just happened to me a couple days ago. If I constantly move the mouse pointer everything works fine, but the second I stop moving the mouse the screen's color changes. When this happens my computer also freezes for about a second. As I am typing this, I am able to get a few words before it shifts color and words stop appearing on the screen even though I'm still typing. Then all of a sudden the color shifts back to normal white and my typed words appear. One second later it shifts back to pink.

This issue started happening to me today and it looks like it has to do with auto-dimming, even when you have the setting turned off. The issue manifests whether connected to power or on battery.


If my computer is in a well-lit, bright room, the issue does not happen, but the moment I move my computer to a darker part of the room the issue manifests when the screen seems to attempt to adjust to low-light.


As samuelberlin mentions, I can momentarily reset it by starting the screen saver via Hot Corners but it comes right back in a few seconds when the screen tries to readjust.


So it's definitely a dimming issue that happens, and most likely software.


NOTE: Both are turned off when this happens: night-shift and "slightly dim the display while on battery power".

I have found a solution to my problem by accident, while on battery power. My MacBook told me that Energy Saver was using Significant Energy.


Short version: While running on Battery Power, open up System Preferences and go into Energy Saver. Disable “Automatic graphics switching.”


Long explanation: As soon as I unchecked the “Automatic graphics switching” box the screen’s color stopped changing and the sudden freezing has also stopped. Problem solved. Out of curiosity I enabled Automatic graphics switching and it then reverted back to the color shift and freezing.


This is the part I don’t understand. With Automatic graphics switching disabled, I plugged in my Power Adapter and the screen’s color still didn’t change. I then checked the box to enable Automatic graphics switching and the screen’s color also didn’t change back. When I was on battery power and enabled Automatic graphics switching the colors would change, while on power adapter the colors do not change. I unplugged my power adapter and the colors did not change no matter if the “Automatic graphics switching” box is enabled or disabled.


So this leads me to think that it has something to do with the Energy Saver function. I still have the “Automatic graphics switching” enabled to see if the color shift and freezing will return, but as of right now I am no longer having these issues.
