Red for emergency

Yesterday I accidently pressed a few buttons on my camera and switched into post focus mode.  I didn't know what that was and I didn't know how to switch it back.  I came home and forgot that it was still in that mode.  Took the camera out today and realised I hadn't got a clue what to do.

Only after I came home this evening did I manage to get onto YouTube and find out about it.  So, this is an emergency blip of a flower in the back garden.
