The plant database had black text on a light tan background. Now it is white on tan (see attached image) and useless. I did not change anything on my system, Mac/Sierra The only recent change to the computer was a Microsoft update of Office.   I can not see how or where to change this back to black.  I've tried using FORMAT -> TEXT COLOR, but all that has resulted is more of my hair turning grey.  I do not think this was the intended consequence.  Any help appreciated
