I have been looking at sRGB's abilities (thats too kind; lets say inabilities) to convert via LAB recently, and it sounds suspiciously similar to this issue. I have proposed previously that any type of "sRGB keyhole" in a workflow would limit color range to the sRGB gamut; to that I would now add that any clipping to an sRGB gamut or any assumed sRGB source space would be likely to cause catastrophic color changes when using profile conversions. Perhaps the name of this phenomenon should not be Matchlock Cyan Skies, but ICM2 Cyan Skies... C. David Tobie Design Cooperative CDTobie@designcoop.com - Turn off HTML mail features.
