Night Shift turns saturated red and red-orange pink on iPhone 18 Pro
On my iPhone 18 Pro, saturated red and red-orange turn pink with Night Shift on. I first noticed it in photos, where egg yolk looked pink. My iPhone 15 Pro does not show this shift. Both run iOS 27 with Night Shift at More Warm. A Reddit user reports a similar pinkish hue on their 18 Pro compared with an M4 iPad Pro.
