Copper and Rust: Metal Turns the Color of Earth

A color-changing metal roof. The material is copper or weathering steel, laid in narrow strips along a curved surface, with seams as raised folds; the surface is already oxidized: copper shows mottled deep brown to verdigris, weathering steel has a uniform orange-brown rust layer. The colors are close to the surrounding soil and tree bark, so they don't stand out in the distant view. The degree of oxidation varies with different orientations. Avoid: using glossy and coated metal sheets, making the oxidized color uniform, using large flat panels that wrinkle on curved surfaces, choosing metal colors with strong contrast to the environment.

一片會變色的金屬屋面。材料是銅或耐候鋼,以窄條的方式順著曲面鋪設,接縫是立起的折邊;表面已經氧化:銅出現深褐到青綠的斑駁、耐候鋼是均勻的橘褐鏽層。顏色與周圍的土壤和樹皮接近,因此在遠景裡不會跳出來。不同朝向的氧化程度不同。避免:使用亮面與塗裝的金屬板、讓氧化的顏色均勻一致、使用大片平板在曲面上出現皺褶、選用與環境對比強烈的金屬色。
