I have a strange issue with Safari and Chrome Mac (19.0.1084.54) in OS X Lion.
Here it is, very simply put:
When I display it in a Webkit browser, text set in Helvetica Neue and color Hex #444 looks a little bolder, and therefore darker, than the same text with an Hex color value of #333. This does not happen at all in Snow Leopard with the exact same browsers (same version). Happens on any website I tried, so I know it's not something related to the CSS of my website.
I tried to change it live through the Inspector and it really shows up. I made a little screencast to explain it better: http://goo.gl/prQAn (.mov - ~60MB)
Anyone has ever experienced something like that?
