Art Deco vs Bauhaus装饰艺术（Art Deco） 对比 包豪斯（Bauhaus）
How to tell them apart: the deciding signals, and the exact changes that would turn one into the other. 怎么分清这两个：判别信号，以及一个变成另一个需要的具体改动。
Art Deco装饰艺术（Art Deco）
Bauhaus包豪斯（Bauhaus）
This is Art Deco because…这是 Art Deco，因为……
This is Art Deco because the geometry is ornamental luxury: mirror symmetry, gilded linework, sunburst and fan motifs, jewel tones on black — the decoration itself is the point, not a byproduct.
这是装饰艺术，因为这里的几何是装饰性的奢华：镜像对称、描金线条、太阳纹与扇形纹样、黑底宝石色 —— 装饰本身就是目的，不是副产品。
It would become Bauhaus if…如果……就变成 Bauhaus 了
It would become Bauhaus if the ornament were stripped away and the symmetry broken — asymmetric grid, flat primary-color blocks, unadorned grotesk type, and not a gram of gold left.
如果把装饰剥光、打破对称 —— 不对称网格、扁平原色块、无饰 grotesk 字体，一克金都不剩 —— 就变成包豪斯了。
