Paint the windmills using my colors as shown, or select your own. Don't worry about doing anything fancy, this is just an exercise to show how things work. Each area is just filled in with a flat wash.
The colors I've used are:
- Sky: cerulean blue
- Foreground: cadmium yellow and cerulean blue
- Bushes: cadmium yellow and ultramarine
- Windmill sails: raw sienna
- Windmill building: burnt sienna
- Windmill door, windows, and top: burnt sienna and ultramarine
