Brushed Metal

# Brushed Metal## UsageUse this DESIGN.md as a reusable design brief for an AI coding agent. Apply it when building a new page, restyling an existing interface, or keeping multiple screens visually consistent.## Design IntentYou are implementing an interface using the **Brushed Metal** design language. 用方向性细纹、冷灰渐变、低反射高光和机械分割线模拟拉丝金属，区别于镜面 chrome 的强反射。Treat surface, depth, light, and texture as the main carrier of brand expression.## Aliases- 拉丝金属- satin metal UI## Category- 材质与表面## Target Platforms- PC 端## Summary用方向性细纹、冷灰渐变、低反射高光和机械分割线模拟拉丝金属，区别于镜面 chrome 的强反射。## Visual DNA- 方向细纹- 冷灰渐变- 机械分割- 低反射高光## Best Use Cases- 音频插件- 硬件控制台- 工业仪表- 专业创作工具## Avoid When轻松消费 App、儿童教育、温暖品牌或大段文本阅读。## Anatomy拉丝纹理要保持方向一致；适合旋钮、面板和工具栏，输入和正文区域需要更平整的底。## Color SystemUse a Seed → Map → Semantic → Alias token architecture. Components must consume named tokens instead of hard-coded colors.### Reference Palette- **reference-1** `#f8fafc`- **reference-2** `#cbd5e1`- **reference-3** `#94a3b8`- **reference-4** `#475569`- **reference-5** `#0f172a`### Seed Tokens- **colorBgBase** `#f8fafc` - 页面基础背景.- **colorBgContainer** `#f0f2f5` - 卡片、面板与容器.- **colorFillSecondary** `#e5e8eb` - 次级填充与弱状态.- **colorPrimary** `#cbd5e1` - 品牌主操作与选中态.- **colorTextBase** `#0f172a` - 正文、图标与高对比轮廓.### Primary Scale- **primary-1** `#f4f6f9`- **primary-2** `#eef2f6`- **primary-3** `#e8edf2`- **primary-4** `#e1e7ee`- **primary-5** `#d8dfe9`- **primary-6** `#cbd5e1`- **primary-7** `#b4becb`- **primary-8** `#9ea7b5`- **primary-9** `#87919f`- **primary-10** `#6d7686`### Neutral Scale- **neutral-1** `#f8fafc`- **neutral-2** `#eff1f4`- **neutral-3** `#e5e8eb`- **neutral-4** `#d3d6da`- **neutral-5** `#b7bac1`- **neutral-6** `#969ba4`- **neutral-7** `#717682`- **neutral-8** `#505765`- **neutral-9** `#303747`- **neutral-10** `#0f172a`### Semantic Tokens- **colorSuccess** `#16a34a` - 成功、在线、已完成.- **colorSuccessBg** `#ddf0e7` - 成功状态浅背景.- **colorWarning** `#d97706` - 警告、待确认、需关注.- **colorWarningBg** `#f4eade` - 警告状态浅背景.- **colorError** `#dc2626` - 错误、危险、阻断.- **colorErrorBg** `#f5e5e7` - 错误状态浅背景.- **colorInfo** `#cbd5e1` - 信息、链接、进行中.- **colorInfoBg** `#f3f6f9` - 信息状态浅背景.### Alias Tokens- **colorBgLayout** `#f3f6f8` - 应用整体画布.- **colorBgElevated** `#f1f3f6` - 弹层、浮层与菜单.- **colorBgSpotlight** `#303747` - Tooltip 与强提示.- **colorBorder** `#d3d6da` - 控件与容器边框.- **colorBorderSecondary** `#e5e8eb` - 轻分隔线.- **colorText** `#0f172a` - 一级文本.- **colorTextSecondary** `#5a606d` - 二级文本.- **colorTextTertiary** `#848993` - 辅助说明.- **colorTextDisabled** `#a9adb5` - 禁用文本.- **colorPrimaryHover** `#d8dfe9` - 主操作 Hover.- **colorPrimaryActive** `#b4becb` - 主操作 Active.- **colorPrimaryBorder** `#e1e7ee` - 主色边框.- **colorPrimaryBg** `#f4f6f9` - 主色浅背景.- **colorLink** `#cbd5e1` - 链接与可跳转文本.- **colorFocus** `#e1e7ee` - 键盘焦点环.- **colorMask** `#0b111e` - Modal 遮罩基础色.Color rules:- Use the palette as design tokens, not random decorative swatches.- Keep primary text and primary actions at accessible contrast.- Use primary-1 through primary-10 for interaction states instead of inventing new brand colors.- Use semantic tokens consistently for success, warning, error, and info; pair color with iconography or text.- Map component styles to Alias Tokens so theme changes do not require component-level color edits.## Typography- Use a modern system sans-serif stack by default; only introduce a custom font when the brand direction requires it.- Headings should be confident but not ornamental; body text must remain readable across mobile and desktop.- Keep labels short, high-contrast, and aligned to the component structure.## Layout And Spacing- Use an 8px spacing base; reserve 4px for micro-gaps and 32px+ for major layout separation.- Keep cards, panels, controls, and lists dimensionally stable across responsive breakpoints.- On mobile, reduce column count before reducing legibility.- Recommended radius: 8-16px radius for cards and controls; keep system consistency more important than novelty.- Elevation and shadow: Use shadows to separate interactive or elevated surfaces only; avoid stacking many shadow styles.## Component Rules- Components should make the surface logic visible: panels, buttons, inputs, and overlays need consistent material treatment.- Primary actions must be visually obvious and reachable; secondary actions should be quieter but still discoverable.- Cards need a clear title, supporting text or metric, state, and one obvious next action when action is expected.- Forms and filters should use familiar controls, stable dimensions, clear labels, and visible focus states.- Empty, loading, error, and success states must use the same visual language, not generic placeholders.## Interaction And Motion- Use subtle 120-220ms transitions for hover, focus, open, close, and selection states.- Motion should clarify state changes rather than decorate the page.- Respect reduced-motion preferences.## Implementation Recipe1. Start with the real user workflow and page structure; do not make a generic landing page unless explicitly requested.2. Establish layout zones first: navigation, content, controls, feedback, and primary action.3. Apply the color tokens to semantic roles: canvas, surface, text, border, accent, danger, and success.4. Build reusable components that express this style: buttons, cards, inputs, tabs, filters, modals, empty states, and status badges.5. Verify mobile and desktop breakpoints before adding decorative polish.6. Check that the final screen still communicates 方向细纹, 冷灰渐变, 机械分割 without relying on a single color or effect.## Quality Checklist- The screen is immediately recognizable as **Brushed Metal**, not a generic Tailwind layout.- The design uses surface, spacing, typography, and component shape together; it does not rely only on colors.- Primary actions and navigation are clear on both mobile and desktop.- Text is readable, controls are stable, and content does not overlap or shift unexpectedly.- Empty, loading, hover, focus, selected, disabled, success, and error states are styled in the same language.- The implementation avoids the known failure mode: 轻松消费 App、儿童教育、温暖品牌或大段文本阅读。## Anti-Patterns- Do not paste this palette onto an unrelated layout and call it finished.- Do not overuse decorative effects where the user needs to read, compare, or act quickly.- Do not mix this style with unrelated visual languages unless the product explicitly requires a hybrid.- Do not hide important state behind low contrast, blur, tiny text, or animation.## Keywords- brushed metal- satin- hardware- knob- industrial## Agent Prompt SnippetImplement the UI in the **Brushed Metal** design language. Prioritize 方向细纹, 冷灰渐变, 机械分割. Use the color roles, typography guidance, spacing rules, component rules, and anti-patterns from this DESIGN.md as hard constraints. The result should feel purpose-built for 音频插件, 硬件控制台, 工业仪表, while avoiding: 轻松消费 App、儿童教育、温暖品牌或大段文本阅读。
