Granulating Pigments in Watercolor: The Secret to Creating Textured, Expressive Paintings
"How Granulating Colors Help You Achieve Stunning Textures in Watercolor Art"
Introduction: What Makes Watercolors So Unique?
One of the most magical qualities of watercolor painting is how pigments interact with water and paper. Some colors create smooth, even washes, while others settle into the texture of the paper, producing a beautiful grainy, organic effect. This unique property is known as granulation.
Granulating pigments add depth, texture, and character to a painting, making them perfect for depicting old stone walls, weathered buildings, rugged landscapes, and atmospheric skies. But not all watercolors granulate—some remain smooth and flat.
Understanding which pigments granulate and how to use them effectively will allow you to create striking, one-of-a-kind watercolor paintings. In this blog, we’ll explore:
✅ What granulation is and how it works
✅ The difference between granulating and non-granulating colors
✅ How to use granulating colors for maximum impact
✅ Examples of granulating pigments and their best uses
Let’s dive into the fascinating world of granulating watercolors! 🎨
1. What is Granulation in Watercolor?
Granulation occurs when larger pigment particles settle into the paper’s texture rather than spreading evenly. This results in a grainy, mottled texture that gives the painting a natural, weathered look.
This effect is especially useful for:
✔ Stone textures (brick walls, ancient ruins, cobblestone paths)
✔ Mountains, cliffs, and rugged landscapes
✔ Dramatic cloudscapes and misty atmospheres
✔ Water effects (especially in streams and rocky shorelines)
💡 Tip: Granulation is not a flaw—it’s a beautiful characteristic that adds richness to a painting!
2. The Difference Between Granulating & Non-Granulating Colors
🎨 Granulating Colors – Textured & Organic
Contain large, heavier pigment particles that settle into paper grooves.
Create beautiful, grainy effects ideal for stone, landscapes, and weathered surfaces.
Work best on rough or cold-pressed paper, where the texture enhances the granulation.
🔹 Examples of Granulating Colors:
✔ Ultramarine Blue – Great for skies and shadowy areas.
✔ Cobalt Blue – Perfect for water and atmospheric effects.
✔ Raw Sienna & Burnt Umber – Excellent for earthy textures and old buildings.
✔ Viridian & Green Earth – Ideal for landscapes with textured greenery.
💡 Tip: Granulating colors work best in wet washes, allowing pigment particles to settle naturally.
🎨 Non-Granulating Colors – Smooth & Uniform
Have fine pigment particles that distribute evenly.
Create soft washes and delicate transitions—perfect for portraits and clean color blends.
Work well on hot-pressed paper, which has a smoother surface.
🔹 Examples of Non-Granulating Colors:
✔ Phthalo Blue & Phthalo Green – Highly saturated and smooth.
✔ Quinacridone Rose & Quinacridone Gold – Transparent and luminous.
✔ Alizarin Crimson – Vibrant and rich.
✔ Lemon Yellow & Cadmium Red – Bright and even.
💡 Tip: Use non-granulating colors when you want soft blends without texture.
3. How to Use Granulating Colors for Stunning Watercolor Effects
✅ A. Creating Stone & Weathered Surfaces
Granulating pigments are perfect for capturing the texture of old buildings, brick walls, and aged landscapes.
Best Colors:
Raw Sienna + Ultramarine Blue – Creates a textured stone effect.
Burnt Umber + Cobalt Blue – Gives a rich, weathered appearance to aged walls.
💡 Tip: Use a dry brush technique to enhance the texture of the paper for a rougher effect.
✅ B. Adding Depth to Landscapes & Mountains
Granulating pigments create a rugged, natural look perfect for painting mountains, cliffs, and rocky terrains.
Best Colors:
Cobalt Blue + Raw Sienna – Great for warm, sunlit rock formations.
Ultramarine + Burnt Sienna – Ideal for deep, earthy mountain shadows.
💡 Tip: Use wet-on-wet layering to let pigments settle naturally for realistic textures.
✅ C. Painting Dramatic Skies & Misty Atmospheres
Granulating pigments help create moody cloudscapes and dramatic skies with a natural sense of movement.
Best Colors:
Ultramarine + Paynes Gray – Creates stormy, moody cloud effects.
Cobalt Blue + Neutral Tint – Perfect for misty, foggy atmospheres.
💡 Tip: Sprinkle salt on wet granulating washes for additional texture in skies!
✅ D. Enhancing Water & Reflections
Watercolors are known for their fluidity, and granulating pigments can mimic water ripples and reflections beautifully.
Best Colors:
Viridian + Cobalt Blue – Great for rivers, lakes, and waves.
Indigo + Burnt Sienna – Creates deep, moody reflections in water.
💡 Tip: Tilt your paper slightly while painting to let granulating pigments settle in unique, unpredictable ways.
4. Tips for Getting the Best Granulating Effects
🔹 Use Rough or Cold-Pressed Paper – The textured surface enhances pigment settling.
🔹 Experiment with Different Water Ratios – More water lets pigments move freely, creating softer granulation.
🔹 Try Dry Brush Techniques – Using less water emphasizes grainy effects.
🔹 Mix Granulating & Non-Granulating Colors – Adds contrast between smooth and textured areas.
💡 Tip: Granulation can be increased by using less binder—test different watercolor brands to see which ones granulate the most!
Final Thoughts: Embrace the Beauty of Granulating Watercolors
Granulation is one of watercolor’s most beautiful and unique characteristics. Instead of trying to control every detail, allow your paints to settle, mix, and create natural textures that add depth, atmosphere, and richness to your paintings.
🎨 Key Takeaways:
✔ Granulating pigments create textured, organic effects.
✔ Best for painting stone, landscapes, skies, and water.
✔ Works best on rough or cold-pressed paper.
✔ Combining granulating and non-granulating colors adds variety and depth.
By understanding how granulation works, you can create expressive and visually stunning watercolor paintings that capture the beauty of the natural world.
