If I understand bugzilla correctly, this issue is bug 325564 (https://bugzilla.gnome.org/show_bug.cgi?id=325564). Martin's comments there are that changing the colorspace from HSL to CIE LCH resolve the issue but do not match Photoshop's results. I searched for a while and could only find some speculation that Photoshop may use CIE Lab, though these people claim they figured it out and that it is custom coefficients in HSY-space: [ http://www.filterforge.com/forum/read.php?FID=8&TID=319 ]. There may be other resources available, but I found this article to be a good introduction to some of the issues involved: [ http://en.wikipedia.org/wiki/HSL_and_HSV ]. Hopefully people can read this and not say things like "only the color should be transferred" -- excluding what - brightness? luminosity? intensity? Or just admit that they want GIMP to do whatever it is that Photoshop does.
