The symptom of my problem is that the same hex color in a PNG image does not match the CSS-defined color defined by the same hex code.This problem only happens in Firefox when gfx.color_management.mode is set to 2 (tagged images only) rather than 0 (off). (Firefox ICC color correction described here).The image is http://dzfk93w6juz0e.cloudfront.net/images/background-top-light.png which at the bottom has the color #c8e8bd. However, the shade of green is different to that color when Firefox color calibration is enabled.Is this image inadvertently tagged for color correction?
Why is Firefox changing the color calibration of this image?
