openmarketui-design Design system for OpenMarketUI - Signet AI's algorithmic trading toolkit. Use when building or designing any OpenMarketUI assets: landing pages, marketing materials, brand identities, UI components, documentation. This skill captures the refined, monochromatic aesthetic with extreme restraint. Key principles: opulence through minimalism, technical sophistication without arrogance, craft over speed. When in doubt, ask "what would Nicholai do?"

OpenMarketUI Design System

A Signet AI company. Building the safest algorithmic trading toolkit with guardrails and intelligence.

The Core Principle

Taste requires restraint.

When designing, strip back until it feels almost too simple - until it borders on bland. Then refine. The confidence is in what's NOT there.

Visual Language

Palette

  • Monochromatic only - black ink on pure white
  • No colors. No gradients. No exceptions.
  • High contrast, crisp edges

Typography

  • Clean sans-serif (Inter, IBM Plex, system fonts)
  • Hierarchy through weight, not font changes
  • Bold for primary, light for secondary
  • Generous letter-spacing for refinement

Texture

  • Dot matrix / halftone patterns for data aesthetic
  • Dense dots = depth and sophistication
  • Patterns should whisper, not shout
  • Code snippets as texture, not decoration

Space

  • Massive white space - this is the opulence
  • If you're unsure whether to add something, don't
  • Negative space IS the design

Composition

  • Centered, balanced, symmetrical
  • One focal point maximum
  • The eye should rest, not hunt

What Success Looks Like

See reference images in assets/:

  • Weiden Haus - dot matrix logos, brutalist simplicity
  • OpenAI Research - white space, clean type, subtle branding
  • brand-kit-v3.png - our direction: wordmark, restraint, whisper

The work should feel:

  • Quietly confident
  • Intellectually opulent
  • Smarter than everyone else, but not proving it
  • Like a whisper in a room full of shouts

Writing Style

Clear, direct, technical but accessible. From our announcement copy:

"Today, we're releasing a research preview of GPT-5.3-Codex-Spark, a smaller version of GPT-5.3-Codex, and our first model designed for real-time coding. Codex-Spark marks the first milestone in our partnership with Cerebras. Codex-Spark is optimized to feel near-instant when served on ultra-low latency hardware—delivering more than 1000 tokens per second while remaining highly capable for real-world coding tasks."

Key characteristics:

  • No marketing fluff
  • Technical precision
  • Specifics over superlatives
  • Let the work speak

Anti-Patterns

Avoid:

  • Color accents (we don't do color)
  • Decorative elements (every pixel must earn its place)
  • Loud typography (whisper, don't shout)
  • Proving intelligence (if you're smart, it shows)
  • Speed over craft (take the time to do it right)

The Question

When stuck, ask: "What would Nicholai do?"

Not because he's the arbiter of taste, but because he takes pride in craft over speed. The answer is usually: less. Strip it back. Trust the work.

Brand Lineage

OpenMarketUI is a Signet AI company. This matters. The design should feel like it belongs to a family of thoughtful, precise, premium tools.
