Patina and Gilding: Two Times of Roof Metal

Details of the roof and dome of an Art Nouveau building, with large areas of copper roofing oxidized over a century into a soft blue-green patina. The ridges and spires are adorned with a small amount of gilded leaves and flower buds, shimmering under a grey-blue sky. The color of the patina is slightly darker where rainwater has flowed, bringing out the texture of time. The ratio of the two metal colors is more green than gold. Avoid: copper roof is shiny new copper-orange, gilded area is too large like a palace, using paint to imitate patina, modern metal corrugated sheets and equipment appearing on the roof.

一棟新藝術建築的屋頂與圓頂細部,大面積的銅板屋面經過百年氧化成柔和的藍綠色,屋脊與尖頂飾上保留著少量鍍金的葉片與花苞,在灰藍色的天空下閃爍;銅綠的顏色在雨水流經處略深,帶出時間的紋路。兩種金屬顏色的比例是綠多金少。避免:銅屋頂是閃亮的新銅橙色、鍍金面積過大而像宮殿、使用塗料仿造的銅綠、屋頂上出現現代的金屬浪板與設備。
