The right equipment will help you produce the look you're going for.
Painting a beautiful sky involves perfecting your brush technique and learning mix the colors. A mixture of the right colors will show depth in your painting, even for blue skies. The blue skies should indicate a sunset or sunrise, or even set the tone for the rest of the painting, whether that includes a landscape or water. Once you have determined the type of sky you want to paint, you can start painting.
Instructions
1. Sketch the landscape or the horizon of the sky onto the canvas. The sky should occupy about three-quarters of the canvas to create a nice horizon. The other portion can be used to paint the landscape.
2. Take the ultramarine blue paint and squeeze it onto the paint palette. Squeeze some of the white paint onto the palette as well. How much you use will depend on how you want to mix the colors and how dark or light you want the sky to be.
3. Dip the paint brush into the white and blue paint to get your desired color distribution.
4. Take a 1-inch paintbrush and create criss-cross strokes at the top of the canvas all the way down to the horizon line. Use colors such as purple and blue to highlight a blue sky with a sunset. Use red and oranges near the horizon to indicate the sunset.
5. Blend the colors on the canvas to produce a nice mixture of colors. After you create the skyline, you can add whatever landscape you choose.
