Poor color rendering of some images

I am experiencing poor color rendering of some images when viewed using Firefox on Ubuntu 11.04. The images display properly using Chromium and when viewed using Firefox on MacOS X.

Chosen solution

That image has an embedded color profile (sRGB IEC61966-2-1 black scaled), so that may be causing it.

That can be caused by a problem with the color profile for your display monitor or color profiles embedded in images.
You can disable color management to test that.
You can set the pref gfx.color_management.mode to 0 on the about:config page to disable Color Management.
You need to close and restart Firefox to make the change effective.

thanks, that fixed the issue.

That raises the question, though, "Why does it render correctly in Firefox for Mac WITH color management enabled?", and What possible effects might occur with CM disabled?

You're welcome
