灰調夜空裡的孟菲斯幾何
金銀銅三種金屬質感分開打，冷光不泛暖，邊緣留細高光就夠了。
✍️ 冷環境光加窄高光這套，是不讓金屬件顯暖的唯一辦法——光一旦偏暖，銀色和銅色就混成一個顏色了。正中心留空不是失誤，是給那個漂浮小點騰地方。

A Memphis-style scatter of geometric shapes sits across a cool dark-gray field that reads like a night sky, filling roughly the top two-thirds of a 3:2 frame while the right third stays open as deep negative space. The pieces are placed with intent: one big angular zigzag anchors the left third, two rounded blobs sit lower-center and lower-right, and a scatter of small circles and pinstripe marks fills the upper-left and upper-right quadrants — dead center stays open except for one small floating accent. Every shape renders as crisp vector art, flat fill, sharp edge: hard triangles, rounded rectangles, thin linear strokes, all keeping the Memphis geometry intact. A few of the shapes carry metallic finish — silver, warm gold, burnished copper — with faint brushed grain and thin specular glints that read like foil catching cool ambient light. Keep the lighting neutral-cool so the metal sparkles without going warm; narrow, soft glints trace the edges and cast only minimal vector shadow. Compose horizontal at 3:2 with tight safe margins, sizing the largest shape to roughly a quarter of the frame width so it reads clean at poster scale.

一組孟菲斯風格的幾何圖形散落在冷灰色的夜空般背景上，佔據3:2畫幅的上三分之二，右側三分之一留作縱深負空間。擺位是有章法的：一個大的折角鋸齒形錨定左三分之一，兩個圓潤色塊落在下中和下右位置，一片小圓點和細條紋圖案撒在左上和右上兩個象限——正中心保持空曠，只留一個小的漂浮裝飾點。每個圖形都按向量風格渲染，平塗填色、邊緣銳利：硬邊三角形、圓角矩形、細線條，都保持孟菲斯式的幾何感。部分圖形帶金屬質感——銀色、暖金、做舊銅色——帶著細微的拉絲紋理和細薄的高光，像冷環境光下的箔片。燈光保持中性偏冷，讓金屬閃光而不泛暖；細而柔的光斑沿邊緣走線，只投出極輕的向量陰影。橫向3:2構圖，安全邊距收緊，最大圖形佔畫面寬度約四分之一，確保海報尺度下依然成立。
