Brand colors

The tokens below are the values as defined in src/styles/global.css. This is the authoritative version. If the codebase and this document ever diverge, the codebase wins.


Color palette

The palette is warm and restrained. Ivory backgrounds, near-black text, amber accent. No cold greys, no neon, no gradients.

Color logic

Two neutrals and one accent. Ivory and near-black carry the page. Amber carries attention.

The ivory background (#fffef2) keeps the page from feeling cold or sterile. The cream (#f3f2e7) is slightly darker, used for cards and input fields so content separates from the page without needing a hard shadow. The near-black text (#191918) reads warm rather than clinical because it is not pure black.

Amber (#fcaa2d) is the single accent. It appears on CTA buttons, section dots, list markers and badges. It never appears as text on a light background because it fails contrast. For accent-colored text on ivory or cream, use the dark amber (#a36404).

The palette is intentionally flat. No gradients, no glows, no shadows beyond one subtle depth cue on the browser mockup.

  • Card and input backgrounds: #f3f2e7 (rl-cream)

  • Ghost buttons: transparent background, #1919181a border, #191918 text
  • Text links on light backgrounds: #a36404 (rl-accent-dark)
  • Section dots, bullet markers, badges: #fcaa2d
  • Dividers and card borders: #e3e2d8 (rl-border)
  • Dark CTA sections: #191918 background at 70% over a painting, white text

Accessibility (WCAG)

Combination Result
#191918 on #fffef2 Excellent contrast. Primary text on page background.
#191918 on #f3f2e7 Excellent contrast. Text on cards.
#191918 on #fcaa2d Good contrast. Button text on accent background.
#a36404 as text on #fffef2 Passes AA. Use for text links on light backgrounds.
#fcaa2d as text on #fffef2 Fails AA. Never use the accent as text color on light backgrounds. Use #a36404 instead.
White on #191918 (or painting + 70% overlay) Excellent contrast for dark CTA sections.

Rules:

  • #fcaa2d is a background color and a marker color. Not a text color on light backgrounds.
  • For text that needs the amber feel but must be legible, use #a36404.
  • For text hierarchy on light backgrounds, layer opacity of #191918. Do not pick a lighter grey.

Typography

One font family does nearly everything. A mono is added only for labels and code.

Parabole (display and body)

Parabole is used for headings, body text, navigation, buttons and UI. Three weights cover the full interface.

Variable Font Weight Usage
--font-display Parabole Regular 400 Body text, headings, nav, buttons. Default for almost everything.
--font-display-medium Parabole Medium 500 Card titles, section labels, FAQ questions, comparison headers, prices.
--font-display-bold Parabole Bold 700 Trusted-by names, user names in chat. Used sparingly.
— Parabole Display 400 Accent variant. Used only for emphasis words in headings via the font-accent class.

The accent variant is a calligraphic display cut of Parabole. It appears exclusively on short emphasis words at the end of a heading:

<h2>European AI built for <em class="font-accent not-italic">trust</em></h2>

Always paired with not-italic to prevent browser italic rendering. Never used for buttons, nav, body text or standalone text.

Decima Mono (labels and code)

Variable Font Weight Usage
--font-mono Decima Mono 400 Category labels, URL bars, code, inline technical tags.

Decima Mono is reserved for UI metadata. Typically rendered at 11px, uppercase, with tracking 0.06em, in rl-muted (#bab9b0).


Practical rules

  1. Do not introduce new fonts. Parabole and Decima Mono cover every case. Inter, Manrope, Libre Baskerville and similar are not part of this brand.
  2. Do not use Parabole Bold for body text or paragraphs. It is reserved for names and rare emphasis.
  3. Do not use the accent variant (font-accent) outside headings.
  4. Do not add new colors without updating global.css and this document.
  5. Use #fcaa2d as a background or marker. Never as text on a light background.
  6. For text hierarchy, use opacity variants of rl-dark. Do not pick a separate grey.
  7. Text links on ivory or cream backgrounds use #a36404, not #fcaa2d.
  8. Keep the design flat. No gradients, no glows, no shadows beyond the browser mockup.
