Hello! I have SMF 2.0.2 I've been tweaking it a lot and now it's almost perfect. But one last thing which kinda bothers me (though it might not be so crucial for other, I don't know...). The left part of body of each post is somewhat different in color. I mean that's where you see the name of the poster, etc. In my case, it's all ONE solid color from wall to wall, so to speak. There's no any border or a distinction between the part where the text resides and where the posters' stats are.
The first is that you may be seeing the effects of a 6-bit LCD you're looking at. 6-bit monitors are only capable of about 262 thousand colors whereas 8-bit screens are capable of 16.8 million colors. 6-bit screens can "emulate" higher numbers of colors with tricks, are cheaper and are what most people own if they own an LCD. You can test this by restoring the browser from maximized and then moving the screen around to see the effects. The viewing angle will also effect how the same color looks at different parts of the screen.
The second thing that comes to mind is that they may be different elements. I'd load up Firefox with Firebug and use the element inspector to make sure they're the same element and/or have the same background-color/image.
