Scoria: a rich red-brown inspired by New Zealand landscapes

Earthy, distinctive and naturally grounded, COLORSTEEL® Scoria is a deep red-brown inspired by volcanic rock. Its balance of warm red and brown gives it a rich architectural character that sits comfortably alongside timber, stone, brick and natural landscapes. Scoria can bring warmth to contemporary architecture while still referencing familiar rural and industrial forms. Use it across a roof for a strong defining feature, or continue the colour onto wall cladding to create a cohesive building form with depth and presence.

Why choose COLORSTEEL® Scoria?

COLORSTEEL® Scoria is a rich red-brown inspired by volcanic rock, bringing warmth and depth to natural palettes. Compared with a more traditional red such as Pioneer Red, Scoria's brown influence gives it a quieter and more earthy quality. This makes it particularly useful for architecture that needs colour and warmth without appearing overly bright. Scoria works well with natural materials because its underlying character echoes the rust, earth and mineral tones found in timber, brick, stone and weathering steel.

It can be equally effective as a feature colour or as the basis of a tonal exterior. Using Scoria on both roofing and wall cladding can create a confident monolithic form, while combining it with timber or masonry breaks down the scale and introduces additional texture.

Available finishes

Industrial-inspired: Scoria works confidently with steel, concrete and weathering steel where a stronger material palette is desired.

Alpine: Timber and stone bring out Scoria's underlying warmth while allowing it to sit comfortably against rugged landscapes.

Mid-century inspired: The combination of earthy colour, timber and masonry can reinforce the warm material palettes associated with mid-century architecture.

• Cedar and warm natural timber
• Weathering steel

Designer tip: Lean into Scoria's mineral quality rather than treating it as simply a red. Layer it with timber, stone, brick or weathering steel to develop a palette built around earth and material texture. Keeping the architecture simple allows the colour and materials to do the work.
