Mixing Recommendations

Get precise 2-paint and 3-paint mixing recipes to achieve your target colour.

⭐ Pro Feature

Pro users get full access to all mixing recommendations, including unlimited 3-paint mixes, cross-line mixing, and cross-brand mixing. Free users see 2-paint results plus up to 2 three-paint mixes when no close 2-paint match exists. Learn about Pro.

Accessing Mixing Results

After scanning a colour or selecting one from a photo, tap the Mixing tab (purple) on the results screen. Mixura calculates combinations of paints that can reproduce your target colour, starting with 2-paint mixes and then searching for 3-paint combinations.

All results — both 2-paint and 3-paint — appear in a single list sorted by Delta E (best match first), so the most accurate recipe is always at the top regardless of how many paints it uses.

3-Paint Mixing

Some colours are difficult to match with just two paints. Mixura's 3-paint mixing algorithm finds optimal combinations of three paints and their proportions to get closer to your target colour.

3-paint mix cards look similar to 2-paint cards but display three paint swatches combined into the result, a 3-segment ratio bar, and a purple "3-paint mix" badge.

💡 When Are 3-Paint Mixes Most Useful?

3-paint mixes shine for muted, desaturated, or complex colours that sit between two primary hues — exactly the colours that 2-paint mixes struggle with. If you see a 3-paint result ranked higher than all 2-paint results, it means three paints genuinely get closer to your target.

Understanding Mix Cards

Each mixing recommendation card shows:

Mix Badges

Cards display contextual badges that tell you about the recipe at a glance:

Reading the Ratio Bar

The ratio bar is a horizontal stacked bar that visually represents the mixing proportions:

💡 Mixing in Practice

Start with the largest proportion paint, then gradually add the next. For 3-paint mixes, add the paints in order from largest to smallest proportion. You can always add more, but you can't take it away. Mix thoroughly and check against the app's swatch.

Filter Toggles

Above the results list, you'll find a compact row of filter toggles that control which paints are considered for mixing:

Use Only Paints I Own

If you've marked paints as owned in your collection, you can toggle "Use only paints I own" to filter mixing results to only show combinations you can make right now without buying new paints.

Cross-Line Mixing

Toggle "Cross-line mixing" to allow paints from different paint lines within the same brand to be mixed together — for example, Golden Heavy Body with Golden Fluid.

ℹ About Cross-Line Mixing

Paints from different lines within the same brand use the same pigments but may have different consistencies (e.g., heavy body vs fluid). The colour prediction is reliable, but you may need to adjust your mixing technique to account for different viscosities.

Cross-Brand Mixing

Toggle "Cross-brand mixing" to allow paints from entirely different brands to be mixed together — for example, Golden with Liquitex.

ℹ About Cross-Brand Mixing

Different manufacturers use different binders, pigment grinds, and formulations. While the colour prediction is based on accurate pigment data, real-world results may vary more than same-brand mixes. Cross-brand mixing is most useful when your selected brands individually lack a close match.

Mix Warnings

Some mix recommendations may include orange warning badges:

These are informational — the mix will still work, but you should be aware of potential differences in the real-world result.

How the Mixing Algorithm Works

Mixura's mixing engine:

  1. Filters paint pairs from the same brand (or across brands/lines, depending on your toggle settings) with similar opacity and sufficient colour difference (Delta E > 5)
  2. Tests mixing ratios in 10% increments: 10/90, 20/80, 30/70... 90/10
  3. Calculates the mixed colour using linear interpolation in the LAB colour space
  4. Compares each mix result to your target using Delta E 2000
  5. Returns mixes with Delta E < 5.0, sorted from best to worst

For 3-paint mixing, the algorithm extends this approach by evaluating combinations of three paints simultaneously. It finds the optimal proportions for each trio of paints, testing a wide range of three-way ratios to minimise the Delta E to your target colour. Because of the larger search space, 3-paint results load progressively after 2-paint results.

ℹ Note on Accuracy

The algorithm uses linear LAB interpolation, which is a mathematical model. Real paint mixing involves physical pigment interactions that may produce slightly different results, especially with highly saturated or opaque colours. Cross-line and cross-brand mixes may show greater variation between predicted and actual results.
