@365anne I did this differently than the duotone. I had two copies of the same photo. I converted one to b&w in Snapseed. I took the other into SuperimposeX and masked the flower. Then I brought the b&w version into SuperimposeX, then I brought in the new colorful flower mask which I created earlier. Snapseed is a free tool. SuperimposeX was a one time purchase of a few dollars when I got it.
