  "cover_prompt": "生成一张极简主义的抽象环境光晕（Ambient Aura）图片作为无字音乐专辑封面。画面的核心色彩组合与情绪倾向是：深邃幽蓝与暗金交融的古典武侠氛围，仿佛月光透过层叠山峦洒落在旷野长亭之上，冷冽又带一丝暗暖的思念底色，深蓝渐变入墨紫、边缘晕散出淡淡赤金的流光。画面完全由纯粹的色彩构成，采用极度的柔焦（Soft focus）和重度模糊效果（Blurred effect），使得不同颜色之间产生极其平滑、如丝绸般的无缝过渡。整体质感极致平滑细腻（Smooth texture），没有任何杂质。强烈要求：这是一张彻底抽象的现代色彩场（Color Field）作品，绝对不要出现任何具体的物体、几何图案或锐利的边缘！不需要任何胶片颗粒感！画面必须是无字封面，绝对不要生成任何文字、拼音或英文字母，不要生成人物轮廓！传达出一种极其平静、舒缓、现代且充满呼吸感的氛围。",
