Bright colors and simple shapes give an "earth and sky" book cover a cheerful style. A realistic, clear, sunny, light blue sky creates the background for the cover. The top half of a realistic planet earth covers the lower third of the cover. Colorful cartoon people hold hands in a chain across the top of the planet. The people can be kids for a children's book cover, adults for an adult book cover, or even chefs for a food book cover.
Dramatic book covers help set the mood for a mystery, adventure or tragic story. A star-filled night sky creates the top three-fourths of the cover. A large, dead rose garden dotted with old gravestones creates the bottom of the cover. A 1-inch vertical line runs down the middle of the cover. The line reflects the same area as it covers, only with a blue sky and living rose garden.
Demonstrating the destruction of the planet Earth is an eye-catching idea for a environmental book cover. Use the top half of the cover for a picture of a beautiful mountain against a sunny sky. Use the bottom half of the cover for a picture of the mountain against a polluted sky after the top has been blasted off for mining. You can also use a picture of a forest before and after logging, the beach before and after an oil spill, and so on.
A basic, black-ink painting on white paper creates an "earth and sky" book cover with a modern style. The Asian-style brush strokes produce the outline of a jagged mountain with a lazy river running through the foothills. Bold blue watercolor paint fills the sky and river areas. White, black, grey and green paint fill the mountain and foothill areas. The title is printed in red to really stand out.
A desert landscape and sunset is a popular choice for an "earth and sky" book cover with a western theme. A red, yellow, orange and gold sunset creates the top two-thirds of the cover. A dry desert landscape sprinkled with a few cacti creates the bottom third of the cover. The shadowy figure of a scorpion, coyote or cowboy in the distant desert adds a bit of drama to the scene.
