I'm not a conspiracy theorist (don't you love posts that begin like that!), but today I noticed an unmistakable difference between the Google search results between the major browsers. It wasn't like this yesterday.

Results in IE only appear a washed out, less saturated, and grey (especially when you see a full page of results). I have a very hard time believing Google would try to psychologically manipulate people like this, so what else could be reason for the difference?
Very interested in theories :)
