SyxnkenCross Expert mode, “WB” thing, tap on it and adjust it (“A” = auto mode, you want it off so just move it around until it’s right as you want/need).

(Un)fortunately, you will have to deal with it manually in Expert mode under conditions like those in your “pink” photos. It’s a technical limitation of small phone sensors, and most phones perform similarly in such difficult conditions. They won’t necessarily act up under EVERY light, but if the light hits the right “tone”, the sensor goes bonkers just like in your pics. You can utilise that to your advantage though, and create your own unique style out of it 😎
