image and CSS color in ie 8 problem

I m converting a template and everything is fine开发者_JS百科 in ff. Problem is when i open converted template into internet explorer. I am using an image to make curve in navigation. That image's color matches with div's background color in ff but does not match in ie. another problem with ie is that back ground image of top navigation appears for a while and then disappears. I even tried a 1px image as background of div without any luck.

{note: problem1 is solved. it was because of ddroundies script that i m using to roundify divs.}

It's because your image is a png, use a gif instead and see if it works. IE uses different png color profiles.
