[品牌名称] + [颜色]

作为一名资深 CGI 艺术家与品牌形象总监，专注于高端 Logo 材质呈现。参考美学：Logo 标志仿佛从金属或哑光材质的背面被向外推压——如同从金属板反面冲压出的浮雕印记、奢侈品包装上的质量标章，或官方文件上的凸起封印。Logo 并非单独独立物体置于表面，而是表面自身的一部分浮雕、隆起、向外突出的形态。

**品牌智能系统**

在执行任何阶段前，先确定以下参数：
1. **LOGO 几何**——识别 [品牌名称] 的核心图标形态，以最简约、最精炼的形式呈现——确保该形态适用于任何尺度。
2. **颜色系统**——基于 [颜色] 构建完整色调体系，从最亮的反光高光到最深的阴影色，判断整体氛围是暖色、冷色还是中性色。
3. **表面材质**——依 [颜色] 决定材质特征：银色或灰色 → 拉丝或同心圆纹理的不锈钢；金色或香槟色 → 带有径向纹理的温暖拉丝金属；黑色 → 阳极氧化铝或哑光碳纤维；白色 → 哑光陶瓷或粉质石膏；任一高饱和色 → 阳极氧化彩色金属，在光照区域保持色彩，在最深阴影处向黑色过渡。
4. **光照方向**——确定最能凸显浮雕形态的单一光源角度——让高光落在凸起峰顶，阴影落在下坡墙面。

**阶段 1：表面与氛围**

图像整体为单一连续材质表面——不是背景与物体的分离，而是填满整个画布的统一物理平面。此表面采用已确定的 **表面材质**。表面光照呈细微的径向渐变——中心区域（浮雕 Logo所在）较亮，向四个边缘逐渐自然暗下。若材质为拉丝金属，则纹理方向为径向或同心——中心发散的圆形抛光纹理，会因不同角度的光照而产生变化。全表面应用等效 ISO 800 的细致均匀颗粒纹理——提升触感和深度，避免数字画面的平整感。表面必须具有真实可触感——如金属牌、奢侈品锡盒盖、或高端浮雕卡纸，能让人用手感知纹路。

---

**阶段 2：浮雕 — 核心**

[品牌名称] 的 Logo 标志以完整浅浮雕呈现——如同硬币、纪念奖章、或奢侈品牌的压印印章——**整个 Logo 形状统一、连续地向外隆起**，并非仅有轮廓或线条路径。Logo 的所有实心区域、曲线与形态整体同高凸起，宛如压币模具形成的形态。Logo 顶面略呈拱形（微凸），非全平——使光源在宽度范围形成平滑高光渐变，从光照侧到阴影侧逐步过渡。平面表面与浮雕成型间的边缘为平滑圆弧斜面（非锐角）——如硬币边缘，光照侧斜面捕捉高光，阴影侧斜面自然渐暗，形成立体分离。Logo 内的负形空间（如苹果Logo的缺口、字母的内部空隙）退回到平面水平或略低，形成干净的内凹空间，其下行斜面则反向捕捉光线。整体浮雕高度应有分量感——类似厚实的硬币或沉重的压印封章，绝非浅表突起。几何形态必须完全忠实于 [品牌名称] 的真实比例与剪影。

---

**阶段 3：光照**

主光源来自左上方约 10 至 11 点位置——柔和、扩散，环绕浮雕曲壁，使峰顶形成高光并在远侧平缓进入阴影。色温由 [颜色] 决定：银、灰、蓝色调 → 冷白光；金、铜、土色调 → 暖琥珀光；白与黑 → 中性日光。辅光源来自右下，强度为主光源的 10–15%——仅保留阴影侧细节，不抬亮到破坏立体感。表面无硬阴影、无光斑聚焦、无边缘光——光照目的仅为呈现浮雕的三维形态——每一曲线、每一高度过渡、每一材质细微变化都需被揭示。

---

**阶段 4：文字排版**

在画布下方、浮雕 Logo 下方、同一连续材质表面上——极简文字组合。文字可选择在相同材质上采用极细微浮雕效果（小尺度凸起），或以平面文字、使用 [颜色] 最亮色调，与表面齐平呈现。
元素 1：小尺度的 [品牌名称] 平面 Logo 标志——宽度约画布的 3%–4%，简洁无浮雕。
元素 2：[品牌名称] 的字标——干净的几何无衬线、全大写、紧凑字距，置于图标下方。
元素 3：一行短的斜体或轻字重说明文字，显著小于字标——自动生成与 [品牌名称] 相关的副标题，如创立年份、产品类别、品牌分部或核心标语。三元素垂直堆叠、居中排列、留足空间。无装饰元素、无线条分隔——纯文字克制美学。

**技术规格**

最重要的指令：Logo 必须呈现 **从表面向外推压、朝向观者隆起** 的效果。若结果像是悬浮在背景上的 3D Logo，则错误；若结果是凹陷或切孔，则错误。正确效果应如同一片金属板被从背面压模——你在正面看到形成的浮雕。开启光线追踪以准确呈现自阴影——浮雕边缘必须在平面表面上投下真实阴影。无景深——画面边缘到中心全清晰对焦。色调映射需保留高光细节——峰顶最亮点应锐利明亮但不溢出，无特征丢失。全画面均匀应用胶片颗粒感。无色差、无镜头畸变、无额外暗角，仅保留表面光照渐变形成的自然暗角。抗锯齿设为最高——浮雕边缘必须完美干净。氛围：制造者的标志、铸造封印、奢侈品浮雕封面——让材质的质感低调而自信地诉说品牌价值。

如果你愿意，我可以为你根据 [品牌名称] 和 [颜色] 自动生成完整材质与光照建议方案，以便直接用于 3D 渲染参考。你需要我做吗？

[BRAND NAME] + [COLOR]

Act as a Senior CGI Artist and Brand Identity Director specializing in premium logo materializations. Your reference aesthetic: a logo mark that appears to have been pushed outward from behind a metallic or matte surface — like a relief stamp pressed from the reverse side of a metal sheet, a hallmark embossed on luxury packaging, or a raised seal on official documents. The logo does not exist as a separate standing object placed on a surface. It exists as a raised relief, a bulge, an outward protrusion that is part of the surface itself.

BRAND INTELLIGENCE SYSTEM

Before executing any phase, resolve these parameters: (1) LOGO GEOMETRY — identify [BRAND NAME]'s primary icon mark in its simplest most reduced form — the mark that works at any scale, (2) COLOR PALETTE — based on [COLOR], build the full tonal system from the lightest specular highlight to the deepest shadow tone, determine if the overall mood reads warm, cool, or neutral, (3) SURFACE MATERIAL — based on [COLOR] determine the surface character: silver or grey becomes brushed or circular-grain steel, gold or champagne becomes warm brushed metal with radial grain, black becomes anodized aluminum or matte carbon fiber, white becomes matte ceramic or chalk plaster, any saturated hue becomes anodized colored metal holding the hue in lit areas and desaturating toward black in deepest shadows, (4) LIGHT DIRECTION — determine the most flattering single light angle to reveal the emboss topography — where highlights land on the raised ridge peaks and where shadows fall on the descending walls.

PHASE 1: SURFACE & ATMOSPHERE

The entire image is one single continuous material surface — not a background with an object placed on it, but one unified physical plane filling the entire canvas. This surface is made of the SURFACE MATERIAL resolved above. The surface has a subtle radial gradient in its lighting — brighter near the center where the embossed logo sits, gradually darkening toward all four edges as the light falls off naturally. If the material is brushed metal, the grain direction is radial or concentric — circular polishing marks emanating from the center, catching the light differently at each angle. Apply fine uniform grain texture across the entire surface at ISO 800 equivalent — this gives tactility, depth, and prevents any digital flatness. The surface must feel physical and touchable — like a metal plate, a luxury tin lid, or a premium embossed card stock you could run your finger across and feel the texture.

PHASE 2: THE EMBOSS — CRITICAL

The [BRAND NAME] logo mark is rendered as a full bas-relief — think of a coin, a commemorative medal, or a luxury brand stamp where the ENTIRE logo shape rises as one unified solid mass from the surface. Not just the outline. Not just the stroke path. The complete filled silhouette of the logo pushes outward from the surface as a single continuous raised form — like the head on a coin pressed from a die. The interior of the logo is NOT hollow or open. The entire logo shape — every filled area, every curve, every solid region — rises together as one piece, at a uniform height above the surrounding flat surface. The top face of this raised form is slightly convex — gently domed, not perfectly flat — so it catches the key light across its full width and creates a smooth highlight gradient from the lit side to the shadow side. The transition from the flat surrounding surface up to the raised logo form follows a smooth beveled wall — curved, not sharp — like the edge of a coin. This beveled wall catches the key light on the lit side and falls into shadow on the opposite side, creating the dimensional separation between the raised form and the flat background. Any negative spaces WITHIN the logo — such as the bite in the Apple, the interior counters of letterforms — are recessed BACK to the level of the flat surface or slightly below, creating clean negative voids within the overall raised form. These recessed areas have their own small beveled walls descending inward, catching light in reverse. The overall raised height must feel substantial — like a thick coin or a heavy embossed seal — not a shallow bump. The logo geometry must be completely faithful to [BRAND NAME]'s actual mark in correct proportions and correct silhouette.

PHASE 3: LIGHTING

One primary soft area light from upper-left at approximately 10 to 11 o'clock position — broad and diffused, wrapping around the curved walls of the raised ridge to create the characteristic highlight peak at the top and gradual shadow descent on the far wall. Color temperature is determined by [COLOR]: cool white light for silver, grey, and blue tones — warm amber light for gold, copper, and earth tones — neutral daylight for white and black. One very subtle fill light from lower-right at 10 to 15 percent intensity of the key — just enough to retain material detail in the deepest shadow areas of the ridge walls without lifting them enough to flatten the form. No hard shadows anywhere on the surface. No spotlight pools. No rim light. The lighting exists entirely to reveal the three-dimensional topography of the emboss — every curve, every height transition, every subtle variation in the surface.

PHASE 4: TYPOGRAPHY

In the lower portion of the canvas, below the embossed logo, on the same continuous surface — a minimal typographic lockup. The typography is either very subtly embossed in the same material as the surface using the same raised-ridge technique at much smaller scale, or rendered as clean flat text in the lightest tone of [COLOR] sitting just at the surface level. Element 1: [BRAND NAME]'s flat logo mark at small scale — approximately 3 to 4 percent of canvas width — as a simple flat mark, not embossed. Element 2: [BRAND NAME] wordmark in clean geometric sans-serif spaced capitals directly below the icon mark. Element 3: one short italic or light-weight descriptor line significantly smaller than the wordmark — autonomously generate a relevant subtitle for [BRAND NAME] such as a founding year, a product category, a brand division, or a core tagline. All three elements stacked vertically, centered, with generous spacing. No decorative elements. No lines or rules. Pure typographic restraint.

TECH SPECS

The single most important instruction in this entire prompt: the logo must read as PUSHED OUTWARD FROM the surface, rising toward the viewer, proud and raised. If the result looks like a 3D logo object floating above a background it is wrong. If the result looks like a depression or hole cut into the surface it is wrong. The correct result looks like you are holding a sheet of metal that someone pressed a die stamp against from the back — and you are looking at the front where the relief has formed. Ray Tracing enabled for accurate self-shadowing — the raised ridge must cast a real shadow onto the flat surrounding surface. No Depth of Field — the entire surface is in perfect sharp focus from edge to edge. Tone mapping: preserve highlight detail — the brightest specular on the ridge peak should be brilliant and tight but never blown out or featureless. Film grain applied uniformly across the full final render. No chromatic aberration. No lens distortion. No added vignette beyond what the surface lighting gradient naturally creates. Anti-aliasing maximum — the ridge edges must be perfectly clean. Mood: a maker's hallmark, a foundry seal, a luxury embossed cover — the quiet confidence of a brand that lets its materiality speak.
