How to Make Brown Paint - Acrylic, Oil, and Watercolour
Brown is the same colour regardless of medium - but the specific pigments you mix, the ratios that work, and the techniques for getting there differ significantly between acrylic, oil, and watercolour. This guide covers all three, plus the earth pigment shortcut that professionals use to avoid the overmixing trap.
The Earth Pigment Shortcut
Before mixing brown from scratch, consider this: earth pigments are pre-made browns. They are iron oxide minerals that nature already converted into rich, warm browns over millions of years. Every manufacturer sells them. They produce richer, more luminous browns than you will ever mix from primaries, and they do not grey out when you layer them.
Burnt Sienna
Warm, reddish-brown. Transparent. The most useful single earth pigment.
Yellow Ochre
Warm golden-yellow. Opaque. Mix with burnt sienna for golden browns.
Raw Umber
Earthy, slightly greenish brown. Neutral. Good for shadows and underpainting.
Burnt Umber
Dark, warm brown. Opaque. Deepest of the earth browns.
Making Brown in Acrylic Paint
Acrylic is the most forgiving medium for brown mixing because it dries fast, is water-soluble for clean-up, and layers well. The main challenge is that acrylics dry 10-20% darker than they look wet on the palette. Always test a swatch and let it dry before judging the final colour.
Recommended Starter Palette for Browns
- Cadmium Red Medium - warm, opaque red. The most reliable starting red for warm browns.
- Yellow Ochre - pre-mixed warm golden-yellow. Skip pure yellow and go straight to ochre.
- Burnt Sienna - your reddish earth brown. Mix with ultramarine for a full range of natural browns.
- Ultramarine Blue - deepens and cools brown without the deadening effect of black.
- Titanium White - essential for light browns and tan tones.
Step-by-Step: Neutral Brown from Primaries
- Squeeze cadmium red medium onto a palette - about a pea-sized amount.
- Add yellow ochre in an equal amount. Mix thoroughly. You should have a warm orange.
- Add ultramarine blue gradually - start with a quarter of the orange amount. Mix. The orange shifts toward brown.
- Continue adding blue in small amounts until the orange has become a warm, neutral mid-brown.
- To darken: add more ultramarine or a tiny drop of black. To lighten: add titanium white. To warm: add more yellow ochre.
Making Brown in Oil Paint
Oil paints produce the richest, most luminous browns of any medium. The slow drying time allows colours to blend on the canvas, and transparent earth pigments like burnt sienna can be glazed in thin layers to build depth without opacity. Oil brown does not dry darker than it looks wet.
The same pigments work well in oil as in acrylic. Key difference: raw umber in oil is an exceptional underpainting pigment (it is one of the fastest-drying oil colours) and is used by portrait painters to establish warm shadow tones before adding opaque lights.
Classic Oil Brown Recipe
- Burnt sienna + ultramarine blue (3:1) = transparent dark brown with great depth.
- Burnt sienna + raw umber (1:1) = neutral earthy brown with no warmth bias.
- Yellow ochre + burnt sienna + a drop of ultramarine = warm golden brown, excellent for highlights on brown objects.
In oil painting, black (ivory or lamp) should be used sparingly and only for the deepest shadows. It dulls the mix significantly. Ultramarine + burnt sienna is almost always a better choice for darkening brown in oil.
Making Brown in Watercolour
Watercolour brown is about transparency and layering. Because the white of the paper provides the lightness, you never mix white into a watercolour brown - instead you dilute with water to control value. This means light tan in watercolour is just very dilute burnt sienna, while dark chocolate brown is nearly full-strength burnt umber with a touch of ultramarine.
Layering Technique for Glowing Brown
- First wash: diluted yellow ochre or raw sienna over the whole area. Let dry completely.
- Second wash: diluted burnt sienna, slightly stronger, only on the mid-tones and darks. Let dry.
- Third wash: burnt umber + ultramarine blue (2:1) for the deepest shadows. Small areas only.
This three-wash approach gives a glowing, luminous brown that looks like sunlit wood or warm leather. Working wet-on-wet with the same washes gives a softer, more diffuse brown used for misty backgrounds.
