Hi, that's a good tip, but not quite the issue I was looking at. My impression from lurking in here is that we've often had questions from people with calibrated displays doing portraits or similar stuff that the colors were not 100% as intended, skin tones too red or something like that. I think one would ideally need a chain of calibrated devices (camera - monitor - printer) if color accuracy is so important, and the color swatches are a good step in that direction, beyond a simple white balance on a grey card or something like that.

If you want to generate a colour profile for your screen then I would recommend the ColourHug (www.hughski.com). All works on Linux too, so no windows dependencies. Regards, Tony.
