title: Why is this PNG mis-colored on Linux?
body: <p>My site uses a PNG for a transitional background. <a href="http://c0848462.cdn.cloudfiles.rackspacecloud.com/af877cc0d22f2dfd41a5074f9d8a581f.png" rel="nofollow noreferrer">Here</a> is the site on Firefox on Mac, and <a href="http://c0848462.cdn.cloudfiles.rackspacecloud.com/1e8df7a67f3a0a3d38d6c787d2c4bb86.png" rel="nofollow noreferrer">here</a> is the same site on Firefox on Linux.</p>
  
  <p>As you can see, the PNG background displays in a duller green on Linux. Is this due to the gamma correction issues described <a href="http://hsivonen.iki.fi/png-gamma/" rel="nofollow noreferrer">here</a>? How can I solve this problem? I have tried using a JPG and also a BMP, but the image then just always displays in the dull green across all platforms. I want to always show the vibrant green as in the Mac screenshot. Is this just not possible?</p>
