I'm new with pillow and new with OpenCV.
I have photo on circle and require border of photo (border for circle) to be required color (RGB 16 11 40). So i suppose to use mask with required color and put the photo on the mask layer.
In the below photo - color of the border for circle is white. But i need to do it to be required color
How i can achieve it?
