Usage Guidelines

Rules and best practices for applying the Forge Space brand consistently across all touchpoints.

Color Usage

Do

Use primary purple for CTAs and primary actions

Use secondary blue for supporting elements and links

Use accent (lavender) sparingly for highlights and badges

Use neutrals for backgrounds and body text

Maintain WCAG AA contrast ratios for all text

Don't

Use accent as a background color for large areas

Mix brand colors with off-palette colors

Use primary purple for error states (use semantic error color)

Use text on backgrounds that don't meet AA contrast

Override semantic colors — success is always green, error is always red

Repository Branding

Every Forge Space repository must use the standardized README header. The wordmark is hosted on the brand guide CDN. Use SVG for web; use PNG or WEBP where raster is needed (e.g. social previews, app icons).

Standard Header

<div align="center">
  <a href="https://forgespace.co">
    <img src="https://brand.forgespace.co/logos/wordmark.svg"
         alt="Forge Space" height="48">
  </a>
  <h1>Project Name</h1>
</div>

Do

Use the CDN-hosted wordmark (brand.forgespace.co) — SVG, PNG, or WEBP

Set height="48" for consistent sizing across repos

Link the logo to forgespace.co

Center-align the header block

Don't

Host local copies of the logo in each repo

Change the logo height or add custom styling

Use the icon or monogram as the README header

Skip the header on any Forge Space repository
