I wish I could have a more helpful title for this question, but honestly I have no idea whats going on.
After upgrading to safari 6, some of the images on my site now appear to be lighter shades? This is a weird problem to explain, so I took some screenshots that will hopefully explain the problem better.

On the left is the screenshot from my site, with the two images by themselves (also in safari). As you can see, they are noticeably lighter on the site vs by themselves. Now I’m sure you’re thinking this has something to do with the images being partially transparent or something, but heres a screenshot from chrome (which looks identical to safari 5.2)

Absolutely no difference in color.
These are all standard png-24 images, and like I said everything looked perfectly normal in safari 5.2 and continues to look fine in all other major browsers.
ADDITIONALLY, if I draw these images on a canvas as opposed to using IMG tags, the color difference disappears. I don’t have any kind of styling that would do anything to IMG tags, not to mention that the repeated background image for the menu does not share this problem, nor does the background tile.
If you have safari 6 and want to go look at things yourself, my site is impiety.net
Seems to be a bug in Safari 6. Searching around found reports of cases where repeated background images shows color shift, while non-repeating images keeps right color. In some cases it only happens after a page reload.
Looks too weird to be worked around. Should be fixed by Apple.
