Starry Gradient Background Effect
Start by layering two or three dark colors from top to bottom.
Blend them while the paint is still wet so they fade into each other.
Add the details with white gel pen.
Moonlit Silhouette Landscapes
Paint a full moon using a light yellow or off-white circle.
Use a darker color to block in trees, hills or buildings across the bottom of the page.
Celestial Nebula Swirl Technique
Create the moon first. Then use a wet-on-wet approach to swirl together blues, purples and pinks.
Let the colors mix naturally and lift some areas with a dry brush to create light patches.
Glowing Moon and Star Reflections
Start with a moon or star pattern and mirror the shape below it using diluted color.
Use horizontal brush strokes to give the effect of reflection on water.
Twinkling Star Cluster Patterns
After you create the background, dot clusters of stars close together with a white gel pen.
Group them unevenly to avoid a uniform look.
Aurora Borealis Color Blends
Blend greens and blues and pinks in loose vertical shapes. Use a clean brush to pull color upward and soften edges.
Whimsical Shooting Stars Effect
Use a slightly damp brush to blur the colors together.
Luminous Moonrise Over Hills
Build layers from the bottom up with blues and dark greens.
Leave a pale circle near the top for the rising moon.
Starry Sky With Silhouetted Trees
Add the starts with white gel pen or spats of acrylic paint.
Galaxy Spiral With Stars
Begin with a circular motion using a wet brush and two colors.
Add darker paint around the edges and use small white dots for stars.
Keep the center light to create depth.
Radiant Moon
Paint each shape with light grays, pale browns and pale orange.
Ethereal Clouds and Moonlight
Blend soft tones using diluted color and create the clouds with a clean paper.
