Thanks a lot Graeme, after some tests, it seems you was 100% correct! :)
I've tried to photograph with white balance at manual different
calibration profiles, and after inspection cursor seems to look the same.
Previously I've already tried to measure white point measured during use
of Pantone's profile and set it as target one but failed. Now when I
didn't set temperature, results are much better and cursor no longer
look pink comparing to background. I really appreciate your help, as
without it I wasn't sure what's going on.
BTW Maybe following info would be some of use for people who use Linux.
I've remind that in days I didn't have calibrator and calibrated gamma
using Norman Koren charts with help of xgamma command(it's better than
nothing but couldn't be compared to hardware calibration of course :) ),
I had similar problem just not that obvious like now. And it was
resolved by setting gamma curves inside NVidia Driver Setting manager to
same levels as used with xgamma command. I may try to experiment a bit
and use same technique when have some time to see if cursor tine could
be altered when white point temperature differs from native.
Thanks once again!
Best regards,
Denis
