Mac Pro restarts and shows a pink screen

Older Mac Pro tower. Screen goes pink for a second, then it reboots. Happened three times today, once while just watching a video. Graphics card on the way out, or software?

is it the black cylinder one from 2013? those had a known graphics card fault that looked exactly like this, artifacts and random restarts, Apple even had a repair programme for it. that ended years ago, but it tells you where to look.

A pink or purple screen before a restart usually points at the graphics card, or the driver for it. Which Mac Pro, and is the GPU the original one? Older tower Mac Pros running an aftermarket card do this a lot. After it comes back up, look in Console > Crash Reports (or the 'your computer restarted because of a problem' dialog) and see what the panic names, if it mentions a GPU or display driver that's your answer. Also try it with everything unplugged except one monitor, and boot into safe mode to see if it still happens.
