Colour Blindness

In our film, the killer is going to have a symptom of tritanopia - a form of colourblindness in which the victim is only able to see shades of red and blue and a few other dark shades, as seen below.

We are going to start of our film in a normal colour whilst viewing the police officer and the when changing scene to the killer, we will edit in the tritanopia spectrum so that all will be seen is the colours of what the killer would see which will bring the audience deeper into the mind of the killer.
