This document is the durable visual design reference for Braincode UI surfaces.
The target style is Brutalist Graphic Poster / 反精致科技海报风. The goal is not polished cyberpunk gloss. The goal is to express AI, brain-computer interfaces, code, neural networks, agents, and model routing through rough linework, strong contrast, low color count, and hand-made industrial print energy.
- Rough, technical, experimental, independent-developer feeling.
- Strong visual pressure rather than elegant whitespace.
- Poster-like information layout rather than SaaS dashboard softness.
- Hand-drawn technical diagram + underground publication + industrial print texture.
- Avoid glossy gradients, glassmorphism, neon cyberpunk, and overly refined enterprise UI.
Use a restrained three-color system:
- Aged paper / 米白 / 旧纸色: main background, archive and print feel.
- Heavy black / 重黑色: titles, silhouettes, borders, brutal lines, structural pressure.
- Oxidized dark red / 暗红色 / 氧化红: visual impact, warning, signal, energy, neural pulse.
Avoid high-saturation neon colors. The palette should feel closer to old posters, industrial printing, revolutionary posters, research dossiers, and underground technical zines.
Linework is the core of the style.
Use:
- thick black strokes;
- irregular edges;
- rough ink marks;
- dry brush texture;
- woodcut-like lines;
- distressed strokes;
- visible grain and imperfect print damage;
- geometric facets for heads, brains, machines, diagrams, and neural structures.

For banner-like layouts, prefer:
left: title + slogan + controls/information
right: main visual: head / brain / machine / signal / code
background: red-black rays, fragments, geometric blocks, signal waveforms
bottom: diagrams, symbols, technical paths, status strips
Common layout traits:
- asymmetrical poster layout;
- heavy borders;
- oversized title text;
- compressed information blocks;
- visible grid and diagram fragments;
- warning/signal strips;
- angular, blocky shapes.
Use strong, compressed, utilitarian type.
English direction:
- Condensed Bold;
- Mono Bold;
- Distressed Sans;
- Poster Gothic;
- typewriter/terminal monospace for metadata and machine text.
Chinese direction:
- 思源黑体 Heavy;
- 阿里巴巴普惠体 Heavy;
- 站酷高端黑;
- 优设标题黑;
- 仓耳今楷 / 宋黑混合 when a more literary tone is needed.
Implementation fallback stack should prefer system-available fonts first, but keep the visual weight heavy and condensed where possible.
- Use hard rectangular panels, not rounded SaaS cards.
- Use thick black borders and offset shadows.
- Use dark red for primary actions, warnings, signal markers, and active mode emphasis.
- Theme rendering follows the terminal/browser/system appearance and resolves to exactly two palettes:
lightanddark. - App-level backgrounds should remain transparent; apply theme color to text, borders, panels, controls, and status surfaces instead.
- Use aged paper surfaces for forms and code blocks.
- Keep code/config editing areas monospaced and print-like.
- Prefer visible structure over subtle affordances.
- Bilingual UI should support English and Chinese at minimum.
- Do not expose secrets in visual panels; show auth status only unless a secure credential flow exists.
This style is especially suitable for Braincode because it communicates:
- AI tooling;
- open source and hacker culture;
- research tooling;
- neural networks and brain-like orchestration;
- code and technical diagrams;
- anti-commercial, hard-core independent developer energy.
The expected feeling is:
hardcore / experimental / technical / research-driven / dangerous / independent
