Colors

Canvas Parchment #fdfaf3

Page background; a soft, warm off-white providing an antique paper-like feel to the entire experience

Cocoa Ink #472425

Primary text, headings, outline borders, and a subtle action indicator. Its deep red-brown provides strong contrast without the harshness of true black, defining the brand's sophisticated warmth

Pure White #ffffff

Background for certain interactive states, subtle borders, and an alternative text color on dark backgrounds

Absolute Black #000000

Background for dark themed sections, and inverse text color. This color is used sparingly to create visual breaks

Deep Charcoal #121212

Secondary text and outline borders, providing a slightly softer dark tone than Absolute Black

Alert Crimson #e73737

Red outline accent for tags, dividers, and focused UI edges. Use as a supporting accent, not as a status color

Do

  • Prioritize NeueHaasDisplay for titles and headlines, using large sizes (135px, 188px) with tight letter-spacing (-0.0250em) to create monumental textual elements.
  • Maintain a monochromatic base palette using Canvas Parchment (#fdfaf3) for backgrounds and Cocoa Ink (#472425) for primary text and subtle outlined interactions.
  • Use no border-radius (0px) for most components, including cards and input fields, to preserve a sharp, architectural aesthetic.
  • Indicate interactivity for `Link` and `Button` roles primarily through text color changes or subtle line treatments, avoiding prominent background fills on most buttons.
  • Employ generous vertical spacing, specifically a ~200px section gap, to create an airy, uncrowded layout between major content blocks.
  • Use Pure White (#ffffff) as the dominant background color for cards and informational blocks within light mode, maintaining visual consistency.
  • Apply subtle 1px dashed borders of varying colors (Cocoa Ink, Pure White) to delineate active states or structural elements where a visible separation is needed without heavy lines.

Don't

  • Avoid using bright, saturated colors unless specifically for semantic feedback (like Alert Crimson #e73737), as they contradict the brand's muted, high-contrast palette.
  • Do not introduce rounded corners (e.g., above 0px radius) for primary UI elements like buttons, cards, or inputs, as this clashes with the sharp, angular design language.
  • Refrain from heavy drop shadows or complex elevation schemes; the design is flat and relies on color contrast and minimal borders for visual hierarchy.
  • Do not use generic system fonts for display elements; stick to NeueHaasDisplay for impact and SFUIDisplay for readability.
  • Avoid dense, information-heavy blocks of text; focus on clear, concise copy supported by ample whitespace and strong typography.
  • Do not deviate from the established letter-spacing values for NeueHaasDisplay headlines; the tight tracking is a core part of its visual identity.
  • Do not add decorative gradients; the system relies on solid colors and text-based visual interest.
