Ten Tips for Painting Rainbows
1. Plan the scene so that the lighting is frontal, with the antisolar point at the center of the circle.
2. Lightly pencil the arc using a homemade beam compass (basically a long wooden bar pivoting on a nail).
3. Paint the scene around it the arc. Don't paint the colors of the rainbow yet. Leave the area of the rainbow's arc whitish and lighter than the background, but still a little transparent so you can see forms through it. Sometimes you can use a rag on your beam compass to lift color out of the arc.
4. Remember that the rainbow is composed of light added to the light of the scene, so it should be lighter than the scene, even after you add the color.
5. Let the background painting completely dry. Then use your brush with the beam compass to glaze colors in individual bands along the arc. Let the edges between the bands blend naturally.
6. Colors should start with red on the outside edge of the arc, then orange, yellow, green, blue and violet on the inside.
7. If you want to add the secondary rainbow, remember that is should be weaker than the primary one, with reversed colors.
8. Plan for the region between the rainbows to appear relatively darker (Alexander's Dark Band). In effect, that means that the region inside the primary rainbow should be just a bit lighter than the area just outside the primary rainbow.
9. Objects overlapping the rainbow should partially occlude it, depending on how far they are from the viewer, and how much illuminated atmosphere there is between the viewer and those objects.
10. Think of the rainbow not as a solid "thing" existing in space but more as a region of added light.
