Duotone双色调（Duotone）
Pop Art波普艺术（Pop Art）
This is Duotone because…这是 Duotone，因为……
This is duotone because the image stays photographic — a portrait or object remapped to exactly two colors — and the palette is one high-contrast pair, with no thick black outlines, Ben-Day dots, or comic-panel grids.
这是双色调，因为图像保持摄影属性——肖像或物体被重新映射到恰好两种颜色——色板是一对高对比色，没有粗黑轮廓、本戴网点或漫画分格格子。
It would become Pop Art if…如果……就变成 Pop Art 了
It would become Pop Art if the photo were redrawn as flat comic panels, the palette expanded to red/yellow/blue/neon, thick #000000 ink outlines were added, and shading was replaced with mechanical halftone dots.
如果把照片重绘成扁平漫画格，色板扩展到红/黄/蓝/霓虹，加上粗黑 #000000 墨线轮廓，并把阴影换成机械半色调网点，就变成波普艺术了。
