This is odd. I have some PNG-24s I like to use for rounded corner/organic effects. They look fine in Safari, Chrome, even IE ( tho the edges become a little frayed, but barely noticeable). On FF, the transparency still works fine but the colors dont match. For example, if I make a box with rounded corners, then match the background color of the content area to the hex value of the PNG graphics used to make the rounded corners FF gives me a difrent shade for the corners and the content area.
I have also tried using RGB values, but i got exactly the same result. Safari, IE, Chrome, and opera match the colors just fine.
Has anyone experienced any problems color matching with PNGs cross browsers? Do you need to use a special setting in photoshop when saving to web so that the colors match? I am at a loss.
