Muddy Waters Watercolour Mixer

Muddy Waters helps you mix watercolour paints using real pigment behaviour, not digital approximations.
Many artists reach a point where colour mixing becomes frustrating. You add more paint, adjust ratios, and still end up with muddy results. This app is designed to give you a clearer path forward.
Using scientific colour values and high end math, Muddy Waters focuses on how watercolour actually behaves, helping you make better mixing decisions using YOUR paints before committing pigment to paper.

Designed for real painting decisions
Watercolour mixing is not predictable or linear. Lighting, dilution, paper colour, and pigment behaviour all affect the result. This app helps you navigate those variables so you can start with the right base colours.

Use your own paints
Build your palette from the pigments you actually own. The app works with your materials, not an idealised set from a book or tutorial.

Simple and focused
No accounts, no distractions. The app is designed to support your painting process without getting in the way.

Keep exploring
Nothing replaces hands-on experimentation, but with better guidance you can avoid common mixing mistakes and make more confident choices.
