Windows 3.1 Web Designer

Expert in authentic Windows 3.1 aesthetic for modern web applications. Creates pixel-perfect retro UI components using beveled borders, system gray palettes, and classic program manager styling.

When to Use

Use for:

  • Retro-themed web applications with Windows 3.1 authenticity
  • Converting vaporwave or modern UI to classic Win31 styling
  • Nostalgic landing pages, documentation sites, portfolios
  • Game interfaces with 90s desktop aesthetic
  • Pixel-art adjacent web experiences

Do NOT use for:

  • Vaporwave aesthetics → use vaporwave-glassomorphic-ui-designer
  • Modern glassmorphism → use native-app-designer
  • macOS/iOS styling → use native-app-designer
  • Flat/Material design → use web-design-expert

Core Design System

Color Palette

Color Hex Usage
System Gray #c0c0c0 THE primary background
Dark Gray #808080 Shadows, pressed states
Navy #000080 Title bar background
Teal #008080 Links, highlights
White #ffffff Beveled highlights, inputs
Black #000000 Beveled shadows, borders

The Sacred Rule: Beveled Borders

OUTSET (Raised) - Buttons, toolbars:

  • Top/Left border: WHITE
  • Bottom/Right border: BLACK
  • Inner shadow: light-gray TL, dark-gray BR

INSET (Sunken) - Text fields, content areas:

  • Top/Left border: DARK GRAY
  • Bottom/Right border: WHITE
  • Inner shadow: black TL, light-gray BR

Typography

  • Primary: VT323, Courier New (pixel-style)
  • Headings: Press Start 2P (chunky pixel)
  • Code: IBM Plex Mono, Courier Prime

Quick Reference

Element Background Border Pattern
Window #c0c0c0 3px solid black, inset bevel
Titlebar #000080 none
Button (up) #c0c0c0 inset white TL, black BR
Button (down) #c0c0c0 inset black TL, white BR
Input #ffffff inset 2px dark-gray
Panel (raised) #c0c0c0 outset 2px
Panel (inset) #ffffff inset 2px + shadow

Anti-Patterns

Anti-Pattern: Gradients

What it looks like: linear-gradient(#00d4ff, #ff00ff) Why wrong: Win31 has NO gradients—only solid colors Instead: Solid var(--win31-teal) or var(--win31-navy)

Anti-Pattern: Neon Colors

What it looks like: #00d4ff, #ff00ff (bright neons) Why wrong: This is vaporwave, not Win31 Instead: Muted palette: teal (#008080), navy (#000080)

Anti-Pattern: Rounded Corners

What it looks like: border-radius: 8px Why wrong: Win31 has sharp 90° corners everywhere Instead: No border-radius (or 0)

Anti-Pattern: Blur Effects

What it looks like: backdrop-filter: blur(10px), soft shadows Why wrong: Win31 has no blur—only hard-edge bevels Instead: Sharp bevel shadows with no blur

Anti-Pattern: Dark Backgrounds

What it looks like: #1a1a2e, #16213e dark backgrounds Why wrong: Win31 is light—system gray everywhere Instead: #c0c0c0 system gray base

The Quick Test

If your component has:

  • ❌ Any blur effects → NOT Win31
  • ❌ Any gradient backgrounds → NOT Win31
  • ❌ Any neon colors → NOT Win31
  • ❌ Any rounded corners → NOT Win31
  • ❌ Dark backgrounds → NOT Win31

It should have:

  • ✅ System gray (#c0c0c0) base
  • ✅ Beveled borders (white TL, black BR)
  • ✅ Sharp corners everywhere
  • ✅ Pixel fonts (VT323, Press Start 2P)
  • ✅ Navy blue title bars
  • ✅ Hard-edge box shadows only

File Naming Conventions

For authentic Win31 feel:

  • All caps: README.TXT, INSTALL.EXE
  • 8.3 format: PROGRAM.EXE, CONFIG.SYS

Reference Files

  • references/design-system.md - Complete color palette, typography, beveled border patterns
  • references/component-patterns.md - Full CSS for windows, buttons, forms, panels
  • references/anti-patterns.md - Vaporwave comparison, decision tree, conversion examples

Core insight: Win31 aesthetic is about DEPTH through bevels, not GLOW through neons. System gray is your canvas—beveled borders create the illusion of 3D.
