Try the Graphics App 'Picsay Pro'.
Once run load a picture, select 'Effect' and look at the third item in the long list titled 'Pop Colors'.
This will allow you to paint on the correct colour whilst the remainder stays Black & White Greyscale.
There are many, many other effects and uses for Picsay Pro. Well worth a look.
.........I don't always get your questions right.... but you'll certainly know I've tried.
P.S. Many thanks for the Thanks votes. Thanks received are converted into a charitable donation.
