The standard which ICC profiles are linked to is d50, 2 degree... no matter what color you use for your monitor, workingspace or wiewing lights. >(I'd > >test it to see if there is any difference, but it takes so long!!).

With some brands of software you could make that assumption, but ColorVision software does not work that way... C. David Tobie Design Cooperative CDTobie@designcoop.com - Turn off HTML mail features.
