why is there green tint on my screen

[Android Central Question]

hello I am looking for help.
So suddenly there was a little green tint on my SE7 it wasn't too noticeable when the light was dim but it suddenly started to grow bigger and it is now noticeable and also there is a pink line on the side of my phone

If the tint and line show up no matter the content being displayed and especially if the line stays the same orientation if you rotate the screen, this usually signals a hardware problem, so not something you can just change a setting and fix. You'd have to get the phone's screen repaired (it can range from a display panel damage to maybe just a loose connector).
