Common watercolor mistakes and how to fix them

Everyone makes mistakes in watercolor—it’s part of the magic. But when things feel messy or "off," it can be discouraging, especially if you're just learning.

This guide is here to help you see mistakes differently—not as failures, but as feedback. Let’s walk through common hiccups and how to respond with curiosity instead of criticism.

Overworking the Paper

What happens: You keep adding paint or scrubbing one area until the paper starts to break down. It pills or looks muddy.

Try instead:

• Let the layer dry completely before making changes
• Plan your layers ahead of time
• Work with a lighter touch—let the water do the work

Watercolor teaches us when to stop. Sometimes, walking away is an act of care.

Using Too Much Water (or Not Enough)

Too much water = uncontrolled blooms or puddles.
Too little = streaky or scratchy color.

The fix?

• Test your brush on scrap paper before applying
• Use a sponge or cloth to control excess water
• Tilt your paper to encourage flow or absorb backruns intentionally
• There’s no perfect amount—it’s about learning your tools.

Making Muddy Colors

Muddy colors happen when you overmix or combine too many pigments. Handmade watercolors are especially sensitive to this because they often have unique undertones.

To avoid:

• Mix only 2–3 colors at a time
• Clean your brush between dips
• Use a limited palette so your mixes stay harmonious
• If it happens? Let it dry. Glaze a cleaner color on top or lift gently.

Rushing the Layers

Adding paint before the last layer dries can create unwanted blooms or streaks.

Fix it by:

• Using a hairdryer on low
• Working on two pieces at once
• Practicing patience—use dry time for a tea break or palette play
