Thank you for answering, Al.

The colors are ver different. I'm afraid it can't be a different setting or a difference by "Night Shift" or the llike. I also have a difference on my developement machine with teo monitors between the two. But it is by far not that big if a difference than what I see between the two machines.

>If the latter, monitor make and model, and adjustments can make that kind of difference. These days LCD panels typically have tons of available adjustments beyond the basic brightness and contrast, e.g. PC or AV modes, themes such as "Warm", "Cool" which bring out reds and blues in particular. It's also usually possible to individually adjust the individual RGB levels. Users with colour deficiencies or blindness may have radically adjusted these values.

>This can vary even by time of day. There has been some recent evidence that too much blue light late in the evening can make it hard to sleep. I believe Apple already offers an option ("Night Shift") to turn down the blue in monitors after some user-defined time in the evening, it would not surprise me if Windows and/or monitor makers follow suit.

>Even best efforts at making two different monitors appear the same don't quite work. I have a dual-monitor setup with a newer LED backlit one as my main monitor and an older CCFL-backlit unit as the secondary. I got them pretty close, but on Windows 7 one of the default JPG/PNG viewer programs would show with a white boundary around images on the LED - drag the program to the old monitor, the boundary was a medium ivory colour.

These two machines may be simply using different colors, i.e. these two users didn't like the Windows defaults, good people :).
