Does IE change the colors of my images?

Question

I am very disappointed that my template in 3 hours is not compatible with a cross browser. Why is this? good, because my title background color does not display correctly in IE:

At first, I thought the problem was due to poor reading of add-ons / fields or other Internet Explorer metrics (but it wasn’t, I checked, and the metrics are fine)

The only problem is that IE is somehow changing the background color of my header.

Note. . This problem ONLY occurs in Internet Explorer (I tested Chrome, FF, Opera and Safari).

Here is a screenshot:

I'm not sure why, but here is the CSS:

#header{ background:#5BA2D9 url('./images/header_bg.png') repeat-x left bottom; min-height:90px; } 

My question is: Does IE change the color of my images? What for? How can i avoid this?

Answer 1

I believe that this is the result of color correction information in PNG files.
PNG file optimization should be fixed.
