Thanks for this very valuable information. For a further push in the correct direction please consider that you have to download the profiles, and your most likely sources are: http://www.color.org/srgbprofiles.xalter and http://www.adobe.com/support/downloads/product.jsp?product=62&platform=Windows Note that the profiles are free, but you must install them to make them available on you host system.

If you need to convert images that are on CMYK format into RGB and want to preserve colour information, this may be helpful: <?php $image = new Imagick("CMYK_image.jpg"); // load image $profiles = $image->getImageProfiles('*', false); // get profiles $has_icc_profile = (array_search('icc', $profiles) !== false); // we're interested if ICC profile(s) exist if ($has_icc_profile === false) { // image does not have CMYK ICC profile, we add one $icc_cmyk = file_get_contents('/path/to/icc/SomeCMYKProfile.icc'); $image->profileImage('icc', $icc_cmyk); } // Then we need to add RGB profile $icc_rgb = file_get_contents('/path/to/icc/SomeRGBProfile.icc'); $image->profileImage('icc', $icc_rgb); $image->setImageColorSpace(Imagick::COLORSPACE_RGB); $image->writeImage("RGB_image.jpg"); ?> There may be better and more elegant ways to do this, but hope this helped.
