#8B3D1A

Burnt Sienna has been in painters' hands since the Renaissance. Named for the Tuscan city where the raw earth was first collected and heated to produce its characteristic warm, reddish-brown tone, it has anchored the oil palette for five centuries. Art Spectrum Studio Blend Oil Burnt Sienna carries that history in a 150ml tube: a warm, luminous, semi-transparent earth colour with exceptional versatility for underpaintings, glazing, flesh tone mixing, and the landscape palette. In Australia, it reads like sun-baked red soil and coastal rock. Everywhere, it is one of the most useful colours on any palette.

★ Art Shed Staff Tip
Start your next oil painting with a thin wash of Burnt Sienna thinned with odourless mineral spirits across the whole canvas. Let it dry. Then paint your lights and darks over the top. You immediately have a warm mid-tone ground to work from, and the orange warmth showing through in shadow areas creates the kind of luminosity that plain white canvas cannot give you. This imprimatura technique is one of the most practical things you can do with a tube of Burnt Sienna.

What Makes This Colour Special

Pigment
Iron Oxide Earth
PBr7 + PR107 (Natural Iron Oxide + Synthetic Iron Oxide). Earth pigments prized for stability, permanence, and warm, slightly complex undertone that synthetic alternatives rarely match.
Transparency
Semi-Transparent
Luminous in thin washes and glazes. Builds naturally to more opaque, rich coverage with heavier application. Works beautifully in both underpainting and finishing layers.
Lightfastness
ASTM I (Excellent)
Iron oxide pigments are among the most permanent materials known. PBr7 has been in paintings for centuries without fading. ASTM I rated.
Consistency
Buttery, Triple-Milled
Triple-milled in purest refined linseed oil. Smooth consistency with good body, easy to spread thinly for washes or apply richly for full colour.

Burnt Sienna is one of those rare colours that earns space on every palette regardless of subject matter. In the landscape, it captures the warm earth tones of Australian red soil, sun-baked rock, ochre cliffs, and the warm-lit trunks of eucalypts. In portraiture, it combines with white for peach-to-tan skin tones and mixes with cooler colours for naturalistic flesh shadow. In still life and interior painting, it grounds compositions with warmth that synthetic colours can rarely match.

Its semi-transparency means it works across the full range of oil technique. As a thin initial wash thinned with mineral spirits, it creates a warm tonal ground that makes subsequent colour decisions easier and gives shadow areas natural warmth. Applied in glazing layers over dried paint, it warms cool passages and adds complexity to shadows. Applied thickly, it holds its warmth and mixes into other colours without muddying them.

Iron oxide pigments dry faster than most oil colours, which is a practical advantage in layered work. Burnt Sienna underpainting layers are often workable within 24 hours, making it a practical choice for painters who do not want to wait days between sessions.

Why Art Spectrum Studio Blend Oil Belongs on Your Palette

  • Iron oxide permanence. PBr7 is one of the most stable pigments in painting history. ASTM I lightfast. Works made with it will not fade or shift colour with age.
  • The essential palette partner. With French Ultramarine it makes a two-colour shadow palette that professional painters use throughout their careers. These two colours alone can describe extraordinary tonal range.
  • Faster drying than most oil colours. Iron oxides accelerate drying, making Burnt Sienna practical for underpainting layers you can overpaint relatively quickly.
  • Triple-milled in refined linseed oil. Studio-grade pigment dispersion. Smooth, consistent paint body that behaves the same way across the canvas from first stroke to finishing glaze.
  • Made in Melbourne since 1966. Art Spectrum manufactures in Epping, Victoria. Six decades of Australian paint-making experience in every tube.

Getting the Most Out of This Tube

For an imprimatura, thin Burnt Sienna generously with odourless mineral spirits until it runs almost like watercolour. Brush it across a primed canvas and wipe back with a rag to create an uneven, atmospheric warm ground. Paint into it while wet or allow it to dry first. Either way it provides warmth that shows through subsequent layers and makes the painting richer than a plain white start.

For dark mixing with French Ultramarine, use roughly equal amounts as a starting point. Adjust the ratio: more Burnt Sienna for warm-toned neutrals and browns; more French Ultramarine for cool grey-blues and shadow tones. The resulting mixes are more interesting and natural than black straight from the tube.

Follow fat over lean: lean layers for early work, richer linseed oil layers on top. Burnt Sienna works across all stages. Its faster drying time is an advantage in the lean early layers; add more oil in upper glazing layers to maintain film flexibility.

About Art Spectrum Studio Blend Oil: Melbourne Made Since 1966

Art Spectrum has been manufacturing artists' materials in Epping, Victoria since 1966. The Studio Blend Oil range is the rebrand of the former Art Prism range, with fresh new packaging and artwork. The formula is unchanged. It is a studio-grade oil paint: above student quality, triple-milled, using lightfast pigments, and designed for working artists who want reliable colour at a practical price. The 26-colour palette covers the complete mixing spectrum and is fully compatible with all Art Spectrum oil mediums and varnishes.

What is Burnt Sienna used for in oil painting?

Burnt Sienna is one of the most versatile colours on an oil palette. It is used for warm underpaintings and imprimatura washes, for mixing shadow tones with French Ultramarine, for skin and flesh tone bases with Titanium White, for landscape earths and Australian red soil tones, and for glazing warmth into finished areas. It dries faster than most oil colours, making it practical for underpainting that can be overpainted relatively quickly.

What pigments are in Art Spectrum Studio Blend Oil Burnt Sienna?

Art Spectrum Studio Blend Burnt Sienna uses PBr7 (Natural Iron Oxide, the classic earth pigment) and PR107 (Synthetic Iron Oxide). Iron oxide pigments are among the most stable and lightfast available, rated ASTM I Excellent. They have been used in painting since antiquity and are the pigment found in the oldest surviving works of art.

How do I mix a dark colour with Burnt Sienna?

The classic approach is to mix Burnt Sienna with French Ultramarine. In roughly equal proportions you get a deep, complex near-black that is warmer and more interesting than black pigment alone. Adjust the ratio: more Burnt Sienna gives warm browns and neutrals; more French Ultramarine gives cool grey-blues and shadow tones. This pairing can produce a complete range of shadow values without black from the tube.

What is the difference between Burnt Sienna and Raw Sienna?

Raw Sienna is the unheated natural earth pigment: it is lighter, more yellowish, and more transparent. Burnt Sienna is produced by roasting Raw Sienna, which deepens and reddens the tone. Burnt Sienna is warmer, darker, and more reddish-brown; Raw Sienna is cooler, lighter, and more golden-yellow. Both are useful; many painters keep both for landscape work.

Is Art Spectrum Studio Blend Oil the same as Art Prism?

Yes. Art Spectrum Studio Blend Oil is the direct successor to Art Prism, Art Spectrum's studio range of 26 oil colours. The formula is unchanged: same pigments, same linseed oil base, same Australian manufacturing. The rebrand introduced new packaging and artwork only. If you have used Art Prism Burnt Sienna before, you will find this product identical in colour, handling and quality.
