Building Depth in Procreate Watercolour Paintings

Creating convincing depth in digital watercolour can feel challenging at first. Traditional watercolour naturally builds dimension through transparent layering, pigment separation, soft bleeds, and paper texture. In Procreate, however, we have to intentionally recreate those qualities.

The good news is that with the right brush workflow and a thoughtful layering process, you can achieve beautifully atmospheric, dimensional results.

In this guide, I’ll walk you step-by-step through how to build depth using my watercolour brush set, moving from soft foundational washes to refined detail and finishing effects.

We’ll be working with:

Filler – Soft (1st layer)
Filler – Medium (2nd layer)
Filler – Coarse (3rd layer)
Details (Main)
Effects – Sponge Texture
Effects – Salt Texture
Effects – Splatter 1–4
Effects – Wet Bleed
Textured Canvas

Let’s break down how and why each one plays a role in creating depth.

1. Start with Atmosphere: Filler – Soft (First Layer)

Depth begins with atmosphere — not detail.

The Filler – Soft brush is designed to mimic diluted pigment flowing across damp paper. It lays the groundwork for everything that follows.

Use it for:

Background washes
Soft skies or distant foliage
Gentle light transitions
Misty or diffused areas

At this stage, think in terms of light and large shapes, not objects. Work with a large brush size and light pressure. Let colour gently build through multiple passes rather than applying heavy pigment all at once.

This first layer establishes:

Light direction
Colour harmony
Overall mood
Atmospheric perspective

Keep contrast low. Background elements should feel airy and understated. Resist the urge to define edges — soft transitions are what make areas recede visually.

2. Establish Structure: Filler – Medium (Second Layer)

Once your base wash is in place, it’s time to introduce form.

The Filler – Medium brush adds more pigment density and slightly stronger texture. It’s perfect for shaping mid-ground elements and beginning to define structure without committing to fine detail.

Use it to:

Block in trees or architectural shapes
Build foliage masses
Add midtone shadows
Separate planes within the composition

This is where depth truly begins to emerge.

Think in layers of space:

Background: soft, low contrast
Mid-ground: moderate contrast
Foreground: stronger contrast

Avoid fully dark values just yet. Instead, gradually layer colour. Traditional watercolour depth comes from transparency — not opacity. Build up pigment through multiple strokes rather than increasing pressure dramatically.

The goal here is clarity of form without sharpness.

3. Add Weight and Texture: Filler – Coarse (Third Layer)

Now we introduce tactile richness.

The Filler – Coarse brush brings visible texture and stronger pigment grain. It naturally pushes areas forward in your composition.

Texture is one of the strongest indicators of proximity. The more texture and contrast something has, the closer it appears to the viewer.

Use this brush for:

Foreground foliage
Deeper shadow areas
Ground textures

Be intentional. If every area is heavily textured, nothing stands out. Depth relies on contrast between smooth and detailed areas.

A helpful rule:

Smooth = distant
Textured = closer

Layer gradually and maintain transparency. Even your darkest values should still feel like layered watercolour, not solid paint.

4. Define with Intention: Details (Main)

With structure established, it’s time for refinement.

The Details (Main) brush allows you to introduce fine lines and delicate accents without losing the organic quality of watercolour.

Use it for:

Stems and fine branches
Defined foliage edges
Small shadow accents
Focal point enhancements

Here’s where restraint becomes crucial.

Detail should live primarily:

In the foreground
Around your focal area
Where you want the viewer’s eye to pause

Leave background elements loose and suggestive. This contrast between defined and undefined areas is a major contributor to depth.

When everything is detailed, the image flattens. When detail is selective, the eye moves naturally through space.

5. Breaking Up Flatness: Effects – Sponge Texture

Digital washes can sometimes feel too smooth. The Effects – Sponge Texture brush helps break up uniform areas and restore organic variation.

Lightly dab it into:

Large flat washes
Ground areas
Foliage clusters
Soft background transitions

Keep opacity low and build slowly. This brush should add subtle irregularity, not distraction.

Texture variation creates visual interest while maintaining the soft aesthetic of watercolour.

6. Organic Pigment Separation: Effects – Salt Texture

In traditional watercolour, salt creates beautiful pigment blooms and starburst effects. The Effects – Salt Texture brush replicates that natural separation.

Use it sparingly to:

Add interest to mid-ground areas
Enhance shadow transitions
Create subtle visual texture

Salt effects work best when they feel accidental rather than deliberate. Avoid placing them in focal points unless you want noticeable texture there.

Used subtly, this brush adds authenticity and depth through variation.

7. Natural Energy: Splatter Brushes 1–4

Nothing says watercolour quite like splatter.

These splatter effect stamps were created from real watercolour splashes, giving them a natural, irregular appearance.

Each brush varies slightly in density and spread:

Effects – Splatter 1: Fine and delicate
Effects – Splatter 2: Moderate distribution
Effects – Splatter 3: More dramatic variation
Effects – Splatter 4: Heavier impact areas

Splatter adds:

Movement
Texture layering
Organic spontaneity
A hand-painted feel

Apply splatter thoughtfully:

Around textured areas
Within foliage
Along ground surfaces
In background washes for subtle depth

Vary colour slightly rather than using pure black. Try deeper or lighter versions of existing tones to keep the splatter integrated into the palette.

Too much splatter can overwhelm the painting, so build gradually.

8. Softening & Bloom Effects: Effects – Wet Bleed

The Effects – Wet Bleed brush creates beautiful water-like blooms — but it only works when white is selected.

This brush mimics adding clean water to wet pigment, pushing colour outward and softening edges.

Use it to:

Soften harsh lines
Create natural edge variation
Introduce subtle water marks
Blend transitions organically

Edge variation is essential for depth. Hard edges advance. Soft edges recede.

By selectively softening certain edges, you control spatial hierarchy. It prevents your painting from feeling digitally cut-out and restores the fluidity of traditional watercolour.

9. Surface Realism: Textured Canvas

Before painting, ensure the Paint Layer sits beneath the Texture Layer. This allows the pigment to interact visually with the canvas grain.

The texture layer:

Unifies all brushwork
Enhances watercolour authenticity
Adds subtle depth
Reduces digital smoothness

Adjust opacity if necessary — it should enhance, not dominate.

This final step ties everything together and reinforces the illusion of traditional paint on paper.

Core Principles for Building Depth

While brushes are tools, depth ultimately relies on these foundational principles:

Value Contrast: Foreground elements should generally have stronger contrast than background areas.
Texture Distribution: More texture in front, less in back.
Edge Control: Soft edges recede. Crisp edges advance.
Colour Temperature: Cooler tones tend to recede. Warmer tones advance.
Selective Detail: Detail attracts attention. Use it intentionally.
