title: PSD to PNG Conversion does not match
body: <p>When converting a PSD file with a transparent background using GraphicsMagick, my PNG image is more "dull/lighter" than the source image. </p>
  
  <p>I've used the following</p>
  
  <p>gm mogrify -level (with countless options)<br>
  gm mogrify -modulate (with countless options)<br>
  gm mogrify -gamma (with countless options)<br>
  gm mogrify -normalize <br>
  gm mogrify -colorspace srgb<br></p>
  
  <p>What other options do I have in order to get the source PSD and the rendered PNG to match closely? The color is very important as they are related to product that consumers can purchase. If the color doesn't match, they may order it and not like what they receive.</p>
