How to Make Chestnut
Warm, medium red-brown - the colour of a chestnut horse, polished leather, and roasted chestnuts.
Recipe: Red + Yellow + Blue (3:2:1)
Combine red, yellow, and blue in a 3:2:1 ratio. The red dominance gives chestnut its warm character; the smaller yellow component contributes orange undertone; the small blue cools the mix from pure red-orange into the brown range. The earth-pigment shortcut: burnt sienna plus yellow ochre at 4:1 gives chestnut without the blue. For a cooler chestnut (toward English saddle leather), shift to 3:2:1.5. For a warmer chestnut (toward roasted chestnut shell), shift to 4:2:1.
What Is Chestnut?
Chestnut sits between mahogany and chocolate brown on the warm-brown axis. It is the canonical colour of the chestnut horse coat (a base of red-brown without any black points), the polished leather of an English saddle, and roasted Castanea sativa chestnuts in late autumn. In hair-colour terminology, chestnut brown is a Level 4 or 5 warm brown with red highlights, the most common natural mid-brown shade in European hair. Wikipedia lists chestnut at #954535; CSS does not have a named chestnut colour, so this Wikipedia value is the practical reference. The shade is reliably mixable from primaries (3:2:1 red:yellow:blue) or from burnt sienna plus a touch of yellow ochre. It is one of the most popular brown shades in interior design - warm enough to feel inviting, dark enough to feel grounded, with the red component that gives it warmth without falling into the orange-tan range.

Making Chestnut in Different Media
Acrylic Paint
Full guide →Burnt sienna mixed with yellow ochre at 4:1 is the cleanest single-pigment route. Add a touch of cadmium red medium to warm if the burnt sienna leans too brown. Golden, Liquitex, and Winsor & Newton Galeria all produce reliable burnt sienna at this hue.
Oil Paint
Full guide →Old Holland Burnt Sienna or Michael Harding Burnt Sienna mixed with Yellow Ochre and a touch of Alizarin Crimson. Apply in glazes over a warm underpainting for the classic Old Master chestnut leather effect.
Watercolour
Full guide →Daniel Smith Burnt Sienna alone gives chestnut at medium dilution. For a more red-leaning chestnut add Quinacridone Burnt Orange or Pyrrol Red Light. Layer over a yellow-ochre underwash for depth.
Food Colouring
Full guide →4 drops red gel + 2 drops yellow gel + 1 drop blue gel per cup of frosting. For autumn-themed buttercream, increase to 5:2:1 and add a half-teaspoon of Dutch-process cocoa. AmeriColor Copper plus a drop of Royal Blue is a fast single-bottle approximation.
Common Mistakes to Avoid
- 1Treating chestnut like chocolate brown - chestnut is significantly redder and lighter. Adding too much blue or black pushes it into chocolate territory.
- 2Using only burnt sienna at full strength - this gives more orange than chestnut. Cut burnt sienna with yellow ochre and a touch of red.
- 3Using cool red (alizarin) as the dominant red - shifts to a muted purple-brown. Cadmium red medium or burnt sienna is correct.
- 4Forgetting the slight red bias - chestnut without red bias becomes generic mid-brown. Always check the mix looks measurably warmer than your neutral brown.
