怎么填变量：先定口味，再定渐变色和点缀：例如"西柚迷迭香冷萃"配"杯底橙红、向上变成琥珀色"、"迷迭香枝"和"西柚片"；"抹茶椰奶"配"下绿上白的分层"、"椰子片"。背景色选饮料颜色的同色系深色，颜色最显亮；想要清爽的日系感，把背景换成"浅灰白色"，并把"高反差"改成"柔和明亮"。

示例图是一只带竖向刻面的玻璃杯，杯底是浓郁的深蓝，往上渐渐变浅；杯里是大块透明的冰和几颗蓝莓，杯口堆着薄荷叶和蓝莓，插着一根木吸管，上方飘着一点冷雾；杯壁全是水珠，黑色的湿台面上散着蓝莓、薄荷叶和水滴，背景是深蓝色。

常见问题：

• 渐变变成均匀的一种颜色：把"渐变"写成"明显的上下两段颜色，中间自然过渡"。
• 冰块浑浊：强调"透明无气泡的手凿冰"。
• 水珠太假：写"水珠大小不一，有的正在往下滑"。

适合：饮品店菜单和新品海报、外卖平台主图；实物与图片差异较大时，注意标注"图片仅供参考"。
