I was talking to a friend the other day and we got onto the discussion about colors in videogames, relating to actual in-game graphics/art. He told me that even though it's easy to see things when everything's brightly colored, sometimes it's better to use dulled or faded colors, especially for things that you might see all the time (like walls or crates or rocks.)
The question I have is, does it matter too much if I have a lot of bright, lively colors for game graphics/art? Or should I tone it down to less lively, dull colors? Does it even matter too much, or can something like this only be evaluated on a game-by-game basis?
