Preliminary Task: Post Production in Utopia

The series Utopia is a sci-fi series which is one for thriller lovers, as they say in reviews, and includes hyper-real violence. They use quite bright colours in this series as I have noticed that it also has a comic book feel to it, mostly based around the fact that the series is based on a comic book which tells of a global conspiracy which turns out to be true.
They edited in the colours after shooting as they shoot the scenes in Britain and the blue skies in the scenes are seen, it would be obvious that they have edited in the blues skies, after all, Britain isn't really the place where blue skies are always present.
They use green screens a lot  which allows them to add on a background and make out the characters are in a complete different place to where they actually are, fooling the audience.
