Ok, in that case I'd like an explanation to what's happening to me. This all started with me color characterising my monitor (laptop LCD) and creating a profile for it (using dispcalGUI), then loading it (using 'dispwin -L'). Display colors became much better (grey is actually grey, not something with a blue tint). Then I started doing some work on some images I had taken just recently, and what I got was absolutely h-o-r-r-i-b-l-e. Basically, the three channels were kind of shifted in the histogram, and what was supposed to be a black background was now redish brown or some such. (I wonder if I could possibly produce a test, say by putting together a white .png, import it and see how it ends up). Changing my display profile from "system display" to "sRGB" gave me a better look. pmjdebruijn> I have further details on anatomy of display profiles here: pmjdebruijn> pmjdebruijn> http://blog.pcode.nl/2012/01/29/color-management-on-linux/ pmjdebruijn> pmjdebruijn> If you still have any questions left, feel free to give me a bump. Yup, I've read it and it makes a lot of sense. What doesn't make sense to me is why there's a need for a program like Gimp and darktable to use the display profile to correct colors that are corrected through the VLUT (by the X11 driver, I assume)...
