Retro Beverage Advertisement Poster

Create a bright and light retro commercial advertisement visual around a specific beverage theme: the first impression should establish a memory point with an oversized, thick, rounded theme logo. The font should look like a soft, inflated signage block with light color filling and clean edges, anchoring the upper visual center of gravity. The main beverage form appears in the lower center with a realistic product photography texture, zoomed in, with clear highlights, condensation or liquid luster, and natural shadows, overlapping the background and part of the text to create a strong sense of depth between the graphic elements and the real product. The background uses radial blocks spreading out from near the subject, with sharp edges and dense rhythm, creating a sense of speed and cheerful impact. The text system is divided into three layers: the main logo is the largest, the subtitle uses a narrow and tall retro uppercase font closely following it, small information is scattered in the corners, and handwritten italic short phrases cross around the subject in arcs or slanting lines, with a few white line-drawn arcs, flash symbols, and small markers added to enhance the rhythm. Colors are extracted from the beverage's flavor, material, and brand emotion, maintaining the relationship between large areas of clear structural color, a few strong contrast accent colors, light information text, and warm main subject color; the overall result is high brightness, high saturation, yet clean and ventilated, with clear color steps, fresh, playful, and energetic emotions, avoiding dark, dirty, muddy layers, or low-vitality retro graininess.

Original Prompt

围绕具体饮料主题生成一张明亮轻快的复古商业广告视觉：画面第一眼由超大、厚实、圆角饱满的主题字标建立记忆点，字形像柔软膨胀的招牌块面，浅色填充、边缘干净，压住上方视觉重心；饮品主形体以真实商品摄影质感出现在下部中心，近距离放大，带清晰高光、冷凝水或液体光泽、自然阴影，向前覆盖背景与部分文字，让平面图形和真实产品形成强烈前后层次。背景使用从主体附近向外扩散的放射块面，边界锐利、节奏密集，形成速度感和欢快冲击力。文字系统分三层：主字标最大，副标题用窄高的复古大写字体紧贴其下，小字号信息分散在边角，手写斜体短句以弧线或斜线穿过主体周围，并加入少量白色线描弧、闪光符号和细小标记增强节奏。色彩从饮料的风味、材质、品牌情绪中提取，保留大面积清亮结构色、少量强对比强调色、浅色信息文字和温暖主体色的角色关系；整体高明度、高饱和但干净通风，色阶清晰，情绪新鲜、俏皮、充满能量，避免灰暗脏旧、浑浊蒙层和低活力复古颗粒。
