Watercolour vs. Gouache: The Good, The Bad & The Downright Ugly

Watercolour flows with magical grace—light and fluid. Full of life, basically.
Gouache? It makes a statement—bold and rich.
Both have their own magic, but which one is right for you?
Today, we’re breaking down watercolour vs. gouache. We'll explore on their best uses, tricky parts, and what to watch out for.
What’s the Difference Between Artistic Essentials?
Both watercolour and gouache are water-based paints.
But here’s where they differ:
Watercolour
🎨Light and transparent, perfect for soft, dreamy layers
🎨Colors deepen as you build them up, but still let light shine through
Gouache
🎨Bold and creamy, providing solid, vibrant color
🎨Allows you to paint over mistakes and layer light colors on top of dark ones
Let’s take a closer look at what sets them apart.
The Good: What Makes Each One Amazing
Why Artists Love Watercolour
✅ Soft & Transparent – Perfect for dreamy landscapes, florals, and delicate details.
✅ Easy Layering & Glazing – Each layer builds depth without making the painting look heavy.
✅ Unexpected Textures – Add salt, alcohol, or plastic wrap to create organic effects.
✅ Light & Portable – Just a palette, brush, and water, and you're good to go!
🎨 Pro Tip: Want a unique effect? Sprinkle salt on wet watercolour for a magical, crystallized texture!
Why Gouache Stands Out
✅ Bold & Opaque – No need to plan ahead like watercolour; you can paint over mistakes.
✅ Smooth Matte Finish – No shine, no glare. It’s ideal for illustrations, posters, and digital scanning.
✅ Works on Dark or Toned Paper – Gouache holds its vibrancy on non-white surfaces.
✅ Reactivates with Water – Even when dry, you can touch it up without starting over.
💡 Fun Fact: Gouache is widely used in animation & illustration because of its clean, flat color application!
While Both Paints Have Their Strengths, They Also Come With a Few Quirks
Let’s talk about the struggles you might run into—and how to fix them!
Watercolour Struggles 😬
❌ Hard to Control – Once the paint starts flowing, you need to work with it, not against it.
❌ Mistakes Are Hard to Fix – Trying to lift or correct paint can damage the paper.
❌ Colors Dry Lighter – What you see wet isn’t always what you get when it dries.
🛠 Fix It: Use a tilted surface to control paint flow & always swatch test before committing to a color!
Gouache Struggles 😵
❌ Cracks If Applied Too Thickly – If you glob it on, expect cracking once it dries.
❌ Gouache can be pricier, but many artists attest for its versatility. Plus that rich finish.
❌ Can Smudge When Wet – Gouache reactivates with water easily—making it prone to unintentional blending.
🛠 Fix It: Mix gouache to a smooth, creamy consistency (like melted ice cream) to prevent cracking.
The Downright Ugly: Mistakes That Can Ruin Your Artwork
Watercolour Mistakes to Avoid ❌
❌ Overworking the Paint – Going back in too many times creates a muddy mess.
❌ Too Much Water – Leads to blooms, streaks, and uneven drying.
❌ Scrubbing the Paper – Causes pilling and damage, leaving you frustrated.
🚀 Solution: Let each layer dry before adding more. And if things go south? Blot with a clean tissue instead of scrubbing!
Gouache Mistakes to Watch Out For ⚠️
❌ Too Much Water = Streaky Paint – It loses its signature opacity.
❌ Too Thick = Cracking – If it dries like cake frosting, it’s too thick!
❌ Mixing Different Brands – Some brands dry permanently, while others re-wet. Mixing them? Risky business!
🚀 Solution: Always test on scrap paper before committing. Aim for buttercream frosting consistency!
So… Which One Should You Use? 🤔
It all depends on your style and what you want to achieve.
🎨If you love soft, unpredictable textures → Watercolour is your best friend.
🎨If you prefer bold colors & control → Gouache is the way to go.
🎨If you want both → Why not mix them? Gouache can be thinned down to behave like watercolour!
