Monochromatic Failure Turned Green

I finally got it.   I had to go into the html and update the color.  I didn't know what I was doing, so it was a surprise to see it worked!

I tried to go w/ a green monochromatic color scheme, and I tried lots of ways to update the template and many templates.  It seemed that every time I changed one, the last one that I changed when back to the original.
