冬季街景红色点缀写实肖像

A highly structured prompt for generating an ultra-high resolution, cinematic photorealistic portrait of a woman in heavy snowfall. The prompt emphasizes realistic skin texture, cold color grading, and uses bold red accessories (scarf and hat) as the main color accent against a muted winter background. It also includes detailed constraints and a negative prompt list.

主题：一名成年女性。柔和自然的面部特征，无美颜滤镜，真实的皮肤质感。

服装：深色冬季外套（{argument name="coat color" default="黑色或炭灰色"}），可见的雪尘。一条醒目的红色编织围巾包裹颈部（厚实羊毛质感）。一顶醒目的红色蓬松冬季帽（人造毛或绒毛），与围巾相配。红色配件是 otherwise muted 冬季调色板中的主要色彩强调。

细节：风吹动的发丝掠过脸部，湿润的睫毛，因寒冷而微红的脸颊。多深度的真实雪粒，电影般的浅景深。

灯光：阴天冬季日光，柔和且漫射，无 harsh 阴影，无 HDR。编辑写实，高细节。无文本。"
