One day I was driven nuts because Scrivener, my favorite long format writing application, was typing red text.  I tried everything.  I went to text color and chose black but it simply would not take.  I went on the Internet, conducted a search and there were no answers.  I just kept poking around until I found the solution.  I must have left off with my writing project with first revision which turns all the text to red.  I only had to choose the menu item “Format > Revision Mode  and then mouse down to “None” to get my text color to become black again.
