The universe is very, very grim. Colors are completely unfitting to the setting, guess why most sweetfx presets desaturate and try to achieve a cooler temperature.
Read the books, you´ll see its a very dark, cold world. Developers should try to reflect this mood, the colors they chose have the opositve effect though.
I agree. The E3 and 35 minute gameplay demos and the SoD trailer had a perfect color palette that fit the game.
Changing the colors, saturating everything, making it look more warm.... That disappointed me the most out of everything relating to the "downgrade:" More than the draw distance LoD that got cut in half and the bad interior lighting.
I just got done with the swamp/bog, and it looked kind of awful. Maybe it's because the weather wasn't right, but it was all so bright, so saturated and so colorful... It didn't look nearly as atmospheric as in the gameplay demos. So disappointed. Couple that with the colorful, light-blue Drowners and how the blood and brutality of the combat got toned down aswell, and you have something that looks and feels absolutely nothing like what they showed.
But I guess CDPR's marketing department realised how much "gamers" love color and stuff and they wanted to appeal to the lowest common denominator last minute. I have no idea why else they'd do this, considering the game didn't start looking like this until late 2014/early 2015, I think.
