The Science Behind
The Science Behind
Perfect Colour Matching
Professional-grade accuracy for serious painters.
Our Mission
Built for Artists, by Colour Enthusiasts
We built Mixura because we were frustrated.
Frustrated with buying the wrong paint tubes. Frustrated with wasting hours at the art store comparing swatches. Frustrated with apps that promised colour matching but delivered guesswork.
So we built something better: an app that uses real colour science to give you accurate, actionable results.
Our goal is simple: help you spend less time matching colours and more time painting.
Our Database
Over 5,900 Paints. 20+ Brands. Complete Coverage.
We maintain accurate colour data for every paint in our database. This isn't guesswork or manufacturer marketing—it's measured colour science.

The Problem
Why Colour Matching Is Hard
Your eyes adapt to lighting conditions. Your monitor shows a limited colour gamut. Paint looks different wet versus dry. And that colour chip from the art store? It rarely matches what comes out of the tube.
That's why eyeballing never works—and why we built Mixura.
Traditional methods fail because:
- Human colour perception varies between individuals
- Lighting conditions constantly change
- Screen colours don't match physical pigments
- Memory for colours is unreliable
- Trial and error wastes time and money
Mixura solves this with objective, scientific colour measurement.
Colour Technology
Colour Science
LAB Colour Space: The Foundation
Mixura works in the LAB colour space (also called CIELAB), which is designed to match human perception.
Unlike RGB (how screens display colour) or CMYK (for printing), LAB describes colours the way we actually see them:
Every paint in our database has been converted to precise LAB coordinates, enabling accurate matching across any colour.
The Delta E 2000 Standard
Delta E (ΔE) measures the perceived difference between two colours—the same formula used by paint manufacturers and quality control labs.
| Delta E | What You See | Rating |
|---|---|---|
| < 1.0 | Identical | Near-perfect |
| 1.0 - 2.0 | Barely perceptible | ★★★★★ |
| 2.0 - 5.0 | Noticeable if you look | ★★★★ |
| 5.0 - 10.0 | Obvious difference | ★★★ |
| > 10.0 | Very different | ★★ |
Mixura targets matches under Delta E 2.0
Pro Feature
When No Single Paint Matches
Sometimes the perfect colour doesn't exist in a tube. That's where Mixura's mixing recommendations come in.
Our Algorithm:
- 1 Identifies valid paint pairs within the same brand and line
- 2 Tests mixing ratios from 10/90 to 90/10
- 3 Calculates the resulting colour using LAB interpolation
- 4 Compares each mix to your target colour
- 5 Returns only mixes with Delta E under 5.0
Mixing recommendations are available with Mixura Pro.
