Colour can be a strange and wonderful thing. Sometimes, all it's used for is to fill in the lines, or make something appear more "real", or more interesting. Yet other times it can be as powerful a force in our identification of a game as any character or soundtrack.

So we got to thinking: can a single colour really sum up (or stir up) our feelings about a video game? Turns out they sure can.

We've picked a few here as examples. Sometimes they're the prevalent colour in a game's background (Pac-Man), sometimes they're a colour used for memorable effects (Halo) and sometimes they're barely seen in the game at all, but from being on its box art and promotional material becomes synonymous with the game anyway (Half-Life 2).

And other times, well, they're not strictly a game at all.

I'm sure you've got ideas on similar tones from games we've missed, so if you do, share them below!
