why dose every AOSP rom for my xperia z1 have a pink haze glitch?

i have been noticing that i cant seem to get a good rom, every 5.0-5.0.1 AOSP rom gives me a pink haze like on some screens like looking at photos and the camera and every 6.0-6.0.1 rom the data dosent work right and has battery drain.
but im more concerned with the pink glitch on LP AOSP, why dose that happen?
