Create a new image, and fill it with black.
Select the Texture Impressionism brush (highlighted as blue on the screenshot), and select any colors. Click and drag across the screen.
Select a different color, and start painting like so.
This was my base drawing, and I created a new layer and used a bigger brush size to paint it red.
The result looked like this. I had 3 layers, and the top two layers had ‘Multiply’ and ‘Screen’ layer blend mode selected.
This is the end of the tutorial. 🙂
