Design a 3:4 vertical "radial stripe gradient" visual poster for [Brand / Product / Abstract Theme].
The background uses low-saturation sage green or gray-green; the overall image is quiet, restrained, and modern.
Set a single radial center at the bottom right of the image, with 12—18 fan-shaped color bands of increasing width extending towards the top left, occupying about 65% of the frame.
Some color bands are curved into concentric arcs, creating a spatial sense of paper folding, shutter structures, and optical ripples combined.
All color bands must maintain clear boundaries; do not use soft diffuse gradients.
Colors change step-by-step according to deep olive green, gray-green, and mist white, with the brightness difference between adjacent bands controlled at 5%—10%.
Only add a small amount of warm yellow or light apricot highlights at the radial center, with an area of no more than 5%, as a light source hint.
Materials can be represented as:
Matte coated paper, translucent resin flakes, screen printing ink, or thin paper art structures,
with slight thickness, small projections, and light surface grain.
Light shines obliquely from the bottom right, the shadow direction remains unified, and source-less luminescence is prohibited.
The title is placed in the blank area at the top left, using a medium-weight geometric sans-serif font;
Subtitles can be arranged along a circular arc;
Numbering, date, and parameter information use monospaced fonts.
Information hierarchy only retains three levels:
Main title
Core graphics
Micro-parameters
The whole is like a combination of modernist optical experiments, architectural shading structures, and high-end paper art posters.
Avoid:
Rainbow gradients
Liquid diffuse backgrounds
Metallic glares
Random ripples
Complex characters
Dense text
Unstructured abstract noise中文参考:

为【品牌 / 产品 / 抽象主题】设计一张3:4竖版“条带放射渐变”视觉海报。
背景使用低饱和鼠尾草绿或灰绿色，整体画面安静、克制、现代。
在画面右下方设置唯一放射中心，从该中心向左上方延伸出12—18条宽度递增的扇形色带，占据画面约65%。
部分色带弯曲为同心圆弧，形成纸张折叠、百叶结构与光学波纹结合的空间感。
所有色带都必须保持清晰边界，不使用柔软弥散渐变。
颜色按照深橄榄绿、灰绿色、雾白逐级变化，相邻色带明度差控制在5%—10%。
仅在放射中心加入少量暖黄色或淡杏色高光，面积不超过5%，作为光源提示。
材质可表现为：
哑光涂层纸、半透明树脂薄片、丝网印刷油墨或薄层纸艺结构，
具有轻微厚度、细小投影和轻度表面颗粒。
光线从右下方斜射，阴影方向保持统一，禁止无来源发光。
标题放置在左上留白区，使用中等粗度几何无衬线字体；
副标题可沿一条圆弧排列；
编号、日期与参数信息使用等宽字体。
信息层级只保留三级：
主标题
核心图形
微型参数
整体像现代主义光学实验、建筑遮阳结构与高级纸艺海报的结合。
避免：
彩虹渐变
液态弥散背景
金属炫光
随机波纹
复杂人物
密集文字
无结构的抽象噪声
