I think Killzone 2 would not be the same at all if it were as bright and colorful as Uncharted. It just would feel wrong.

it depends on the mood, if its "the world is ending" or depressing kind of mood, gray is perfect for depicting it.
i loved how in Twilight Princess they used gray and black for the depressing twilight realm and how they added a gray tone for when Midna gets pwned

I think the article is somewhat missing the point. It isn't really a problem when a game comes out and presents a muted color pallet due to its style/story, the problem is that it feels like every game this generation is doing so.

As much as I'd like to say "Color scheme isn't important" I can't help but feel it cripples some games. Resistance, for example, was hard to look at (for me at least) simply because everything was gray and colorless... However, certain games look better in gray, so this article has a point.

I still don't know why some games don't just add some green or other vibrant colours. It only doesn't fit because developers are lazy to create new areas that could be there in the game world because they create the game world...

I mean Metal Gear Solid 4 for instance, shit loads of grey, brown and black horrible colours but they added in Act 2 all that incredible greenland and tree's and all that stuff, and even though it may not have fit entirely, it was a nice thing to see...

Even Killzone 2 could add that or hell it is set in the future on a distant planet, the Helghast could have rooms and buildings that act as internal forests and stuff, there are millions of plausable ways to get around this problem, developers just don't want to, as the fact is dark and lifeless colours make the game more moody and dark which gives it the atmosphere without them even trying.

Gray? I honestly thought it was shades of brown that was the problem, not gray.

Sure they set the mood, but come on, this is where creativity lies. Get creative, use colors beside brown (or gray). Most of the time people think the browns (grays) make the game more "realistic" but I look around me and . . . I see lots of colors!

One of the reasons FFXIII's screenshots have amazed me is that it's one of the few games that has used every color in the rainbow, and it definitely stands out amongst other next-gen games. Appearance-wise, anyways.

White Knight Chronicles and Valkyria Chronicles seem to have achieved good atmosphere without needing to mute any colors either.

These editors are running out fo ideas.
