Colouring the monochrome underpainting

In traditional art the next step would be to create thin layers of paint to colourise the monochromatic picture. This process is called glazing. Corel Painter 2019 has a new family of Glazing brushes for this very step. I set the layer mode to Colorize and apply various colours. I let some of the underpainting show through and avoid having flat shapes of the same hue or colour. This creates a mesmerising mosaic of brushstrokes.
