Bipaular

So i've been playing for 2-3 hours and have a decent amount of food & water , and also plenty of rags to stop any bleeding. My screen is completley black and white , i've drank plenty of water and ate plenty of nutrients like beans and tuna but the screen is still completely black and white. Any ideas? i know there are lots of threads that cover this on google but all just say eat and drink and wait but i've done this and nothing has happened.
