How to mix Terracotta in oil paint
Terracotta is the warm red-brown of fired clay. Below are the oil paint mixing recipes PaintMixLab calculates for it from three common paint sets, in parts you can measure on the palette.
Target colour #C4663F
Predicted mix #C66942
Target #C4663F against the predicted mix from the Winton recipe (excellent match, ΔE 0.8).
Terracotta mixing recipes by paint set

Parts are by volume. Recipes follow the app’s standard engine, which adds white to bring the mix up to the predicted value on the palette. Match quality (ΔE 2000) compares the predicted mix with the target: under 1.5 is excellent, under 3.5 very close, under 6 close.
Dark Mode recipes (original engine, no extra white)
- Winsor & Newton Winton: 4 Lemon Yellow Hue + 1 Cobalt Violet Hue
- Gamblin 1980: 12 Hansa Yellow Light + 1 Cadmium Red Light
- Magicfly 40: 3 Raw Sienna + 1 Purple
What two colours make Terracotta?
With only two tubes from the Winton range, the closest PaintMixLab finds is 11 Soft Mixing White + 3 Light Red (close, ΔE 5). Two-tube mixes are simpler to repeat but usually a little further from the target than three.
How to mix Terracotta by hand
- Put out Lemon Yellow Hue as the base — it carries the hue.
- Work in Cobalt Violet Hue a little at a time until the hue swings towards terracotta; stop as soon as it reads right, it is easy to overshoot.
- Lighten with white until the value matches your reference. Check it next to the target in daylight — a mix always looks lighter on the knife than on the canvas.
- Mix more than you think you need, and save the swatch in PaintMixLab so you can repeat it tomorrow.
Oranges and earth tones are usually a warm yellow and a red, greyed down with a little of the complement blue. Burnt Sienna and Yellow Ochre get you most of the way on their own.

Terracotta questions
What colours make terracotta?
In the Winton range: 5 Titanium White + 4 Lemon Yellow Hue + 1 Cobalt Violet Hue. Other sets use different tubes because tinting strength varies by brand — see the table above for Gamblin 1980 and Magicfly.
Can I mix terracotta without black?
Yes. None of the recipes above rely on black alone; where a dark is needed the engine prefers a deep colour or an earth so the mix stays lively. PaintMixLab has an “avoid black” option if your set includes black and you would rather not use it.
Why does my terracotta look different from the swatch?
Pigment batches, how much medium you use, the lighting and your screen all shift the result. Treat the ratio as a measured starting point: match the value first with white, then nudge the hue with the smallest tube in the recipe.
Does this recipe work for acrylic terracotta?
Roughly. Acrylic ranges share many pigment names, but acrylics dry darker and the tinting strengths differ, so expect to add a little extra white and re-check once dry.
