CHROMATIC DARK · CURATED PAINT RECIPE
How to mix chromatic black paint
A near-black mixed without tube black, designed to retain adjustable warm or cool undertones.
STARTING MIX
3 : 3 : 0.25
Use one consistent unit for every part. For the smallest fractions, scale the entire recipe up instead of estimating a partial drop.
Useful first test, with the claim kept honest
This recipe uses pigment behavior and color relationships to define a controlled starting point. It is not yet a named, brand-calibrated studio test. The target is an sRGB reference; your dried paint remains the deciding evidence.
PIGMENT LOGIC
Why this mixture works
Near-complementary dark pigments absorb across much of the visible spectrum together. Unlike tube black, the balance can be shifted toward the ambient color of the painting.
The displayed #252625 swatch is an sRGB target, not a promise that every brand will dry to the same color. Pigment identity, tint strength, opacity, medium, surface, and lighting remain part of the result.
BASIC-PALETTE ROUTE
Alternative recipe
Other useful pairs include phthalo green plus a deep red, or alizarin crimson plus phthalo green. Pair strength varies dramatically.
Apply the mixture on the same ground and at the same thickness planned for the final work. Label the wet ratio, wait for a complete dry-down, and compare in neutral light before adjusting.
CORRECTION MAP
How to adjust the result
Add blue for cool night black, umber for warm shadow black, or magenta if a green cast appears. Test a white tint to reveal the bias.
Correct value first, then hue, then chroma. This order prevents a lightness error from turning into an unnecessarily complicated recipe.
WATCH FOR
Common mistakes
- Assuming equal physical parts are optically balanced
- Using too many dark pigments
- Calling the mix neutral without checking a tint and thin film
SCALE THE BATCH
Keep fractional parts measurable
Choose a scale that turns the smallest addition into a unit you can repeat. The proportions stay identical.
MEDIUM CHECKS
Translate the ratio into your material
- Acrylic: compare only after full dry-down and keep film thickness consistent.
- Oil: inspect both the thick mass tone and a thin application; transparent pigments can shift strongly with thickness.
- Watercolor: mix by repeatable brush loads or drops, record dilution, and use the intended paper.
- Miniature paint: match the primer, thinning, wash, and final varnish used on the model.
VERIFICATION PROTOCOL
What to record with the swatch
- Exact brand, range, color name, and pigment code where available.
- One measurement unit and the full ratio before any correction.
- Medium, surface, ground or primer, and application thickness.
- Wet observation, fully dry observation, light source, and date.
- The largest remaining value, hue, or chroma error and one next adjustment.
THREE USEFUL VARIATIONS
Extend one successful base
- Lighter: split off a sample and raise value gradually; inspect whether white also cools or dulls it.
- Darker: use a related chromatic dark before reaching for black, then compare the undertone.
- Quieter: reduce chroma with a prepared near-complement in very small steps so the value does not collapse.
