I disagree. As you said, specific colors were used in order to transmit different sensations. And I agree with that notion, I believe it plays a very important role to the artistic aspect of the game. Keeping that in mind, I believe a post apocalyptic world should NOT be colorful. It can contain, of course, colorful items and places and clothes etc, however the general feeling should be something dull, that shows destruction and makes you feel something bad happened in this place. The filters were not used to force you feel anything. For example the dark sky in fallout 3 made me feel that there was some kind of air pollution, however when I see the clean blue sky in fallout 4 pic it makes me feel that the world was either not destroyed, or that what happens takes place many, many years after the war and the pollution and darkness of the world was significantly reduced.

Of course, I don't mean to say that it makes the place less post apocalyptic. It still shows destruction, but it creates different emotions. For example, if society is destroyed but the world looks amazing itself, I would love to explore and create life. Looking at the picture of Fallout 4, I want to explore everything you can see in the horizon. I am pretty sure there are many "cities" out there. It gives me the feeling of a destroyed, but lively world. In Fallout 3, I never believed I would find so much life and so many different factions and cities. When I started playing it I believed it would be a scary world and I would be searching for signs of society.

All in all, I believe that either using or not using filters, just adds different feeling to the game. Both have advantages, but I have not played a post apocalyptic world that looks so clean and promising as fallout 4 so I am hyped to experience it!
