This was kind of posted before, but I wanted to add on to the info about the options in Color Filters.
There are a few ways to adjust the color of the screen.
General>Accessibility>Display Accommodations>Color Filters
- You have 5 options to adjust the color. Since a lot of the problem is between the Yellow-Blue tones, try adjusting based on the Blue/Yellow filter (4) instead of the Color Tint (5) filter. See attached thumbnails.
I know this isn’t true calibration, but it may help some of you who just need a color adjustment.
One more thing:
You will find the Reduce White Point slider under General>Accessibility>Display Accommodations
Note: This is on my iPad Air 2 (not perfect), so you’ll have to find what works best for you.
Can’t help on the off axis color changes issues.
