Start with the sky gradient
A real sky isn't one flat blue. It's a gradient — deeper and cooler at the top, lighter and warmer toward the horizon. Lay this down first with a large soft brush, then blend it smooth. This gradient alone reads as sky and gives clouds something to sit in. For smooth blends, see how to blend in Procreate.
Understand cloud structure
Clouds are 3D forms, not flat shapes — billowing masses with a lit top and a shadowed, flatter bottom. Like trees, think of them as clumps catching light. The light side faces the sun; the underside is in shadow and often picks up the horizon's warmth.
1. Block the cloud shapes
On a new layer, block the big cloud masses with a soft brush — irregular, overlapping puffs, larger overhead and smaller toward the horizon (perspective). Avoid evenly spaced identical clouds; vary size and clustering.
2. Light the clouds
Add bright highlights on the tops facing the sun and keep the undersides in soft shadow. Build the highlights with a slightly textured or cloud brush from the nature category — see the best free nature brushes. Keep edges soft on the shadow side, crisper where the sun hits.
3. Soften and integrate
Blend the cloud bases into the sky so they don't look pasted on, and pull a few wispy edges with a soft brush. Lower opacity on distant clouds. A Gaussian Blur on faraway haze adds depth.
Cloud types
- Cumulus — fluffy, cauliflower puffs with flat bottoms.
- Cirrus — thin, wispy streaks high up.
- Stratus — flat, layered overcast.
- Storm — tall, dark, dramatic masses.
Sunsets and mood
For a sunset, build the gradient from deep blue/purple at top to orange/pink at the horizon, and light the clouds from below with warm color and glowing rim edges. Set the sky color first; everything in the landscape should harmonize with it. Use Add/Screen layers for sun glow.
Brushes and next steps
Paint skies with free soft and cloud brushes from the nature and blenders categories, or any free brushset. Put your sky into a full landscape and fade the horizon with atmospheric perspective.
