After display and CPU had gone into sleep mode during reactivation the display colors are completely off! Disconnecting and reconnecting the display solves the problem immediately! Has anyone experienced similar problems? Is it related to Yosemite or to the graphic chip of the new Mac Mini?
The display is connected via DVI - mini display port adapter.
MacBook Pro, Mac OS X (10.6.8)
Try resetting the SMC and NVRAM

I have been having the same issues as well. Works fine otherwise, but it's annoying and shouldn't be happening.
I have also been having the same issue and would appreciate a solution. HDMI to DVI connection.
Same here, at least by finding this thread I've realized it's just not me. 🙂
Hello everybody, here is THE FIX: clean install your macMini and you are done. Worked for me.
Just got a refurb 2014 Mac Mini straight from Apple. I'm having the same issue as well.
