title: android fill image with colors
body: <p>Is it possible to fill an image with two colors (ex green and blue) but the colors should be painted only over black color and green must be painted only to a certain coordinate and the rest of the image should be painted with blue? Below is an example of image in which black must be replaced with green and blue</p>
