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.
Chestnut Mixing FAQ
How do you make chestnut brown paint?
Mix red, yellow, and blue in a 3:2:1 ratio: the red dominance gives the warm character, the yellow adds an orange undertone, and the small blue cools the red-orange into the brown range. The cleaner earth-pigment route is burnt sienna cut with yellow ochre at 4:1, warmed with a touch of cadmium red medium if the burnt sienna leans too brown.
What two colors make chestnut?
The two-tube shortcut is burnt sienna plus yellow ochre at 4:1, which lands on chestnut without any blue. From primaries it is a three-colour mix - red, yellow, and blue at 3:2:1 - because the small blue is what pushes the warm red-orange into the brown range.
What is the hex code for chestnut?
Wikipedia lists chestnut at #954535, a warm medium red-brown. CSS has no named chestnut colour, so this Wikipedia value is the practical reference; the site uses #954535 as the canonical chestnut value.
How do you make chestnut darker without turning it into chocolate?
Shift the mix toward 3:1:1.5 (less yellow, more blue) for a dark chestnut around #6A2E1F, but keep the red bias - chestnut is measurably redder and lighter than chocolate brown. Adding too much blue or any black is what tips it over into chocolate territory.
How do you make chestnut frosting or food colouring?
Use 4 drops red gel, 2 drops yellow gel, and 1 drop blue gel per cup of frosting. For autumn-themed buttercream, increase to 5:2:1 and add half a teaspoon of Dutch-process cocoa. AmeriColor Copper plus a drop of Royal Blue is the fast single-bottle approximation.
