I've dug out the log, it was for 1 & 4bit grayscale. I've tested your
Xephyr in linux and it certainly works as announced Crystal.
So is 1 and 4 bit greyscale meant to work if the hardware allows it, or
is the bare minimum 8 bit now? Which would be understandable.
Also I agree that "warm" or "red" mode is preferable for evening use of
screens, no need for grayscale for that. Been using it for a decade, it
helps a lot. Found many a relative who hadn't heard of it and were
suffering from related sleep issues.
Cheers,
Noth

Yes we had someone on IRC a while back (like at least 5 years ago) who was
complaining of this, grayscale doesn't work anymore in xenocara, and that
may be the case in regular Xorg too. I guess we have zero users who use this
mode?
It certainly does work. But it depends on the underlying graphics driver.
$ Xephyr :1 -grayscale &
$ xterm -bg black -fg green -display :1
