Mastering Water Reflections in Watercolor (and How Gouache Can Help You Fix or Finish)
Creating realistic water reflections in watercolor can be one of the trickiest techniques to master. Water is fluid, reflective, and constantly changing—capturing that with a brush takes a mix of observation, layering, and patience.
My Tips for Painting Reflections:
-
Start light: Lay in your base water tones using wet-on-wet to keep things soft.
-
Mirror shapes: Whatever’s above the waterline gets loosely mirrored below—but soften the details.
-
Pull down and blur: Use a damp brush to gently pull color downward while the paint is still damp for that natural ripple look.
When It’s Not Working…
Sometimes reflections end up too dark, too harsh, or just off. That’s where gouache can be a lifesaver.
-
Use white gouache to pull back highlights or add ripples.
-
Mix gouache with your watercolor paints for softer, more matte adjustments that sit on top of the paper.
-
Think of it as layering light on top, especially useful for sparkles, boat highlights, or cloud breaks.
Watercolor is about letting go of perfection—but also knowing when to grab a tool like gouache to guide things back.
If you’ve struggled with reflections, you’re not alone. I just finished a painting of Bunker Harbor that had me rethinking every brushstroke on the water. But I stuck with it, used a little gouache magic, and now it’s one of my favorite pieces.
