Brand

Color

Delphi's brand colors are for print, marketing, and editorial — decks, campaigns, social, and pages like this one. The product interface runs on a separate, semantic color system; don't reach for these hexes in app code.

Primary

The four that do the heavy lifting. Tangerine is the brand's pulse — used with intent, never as wallpaper. Near-black anchors type and structure. Bone and white hold the page open. Restraint is the point.

Secondary

A wider palette for editorial range — topic spotlights, category systems, campaign moments. Deep oxblood, navy, and forest carry weight. Burnt tangerine, sky, and olive lift it. Used one or two at a time, never as a rainbow.

Trademark

The Delphi logo represents our commitment to making AI that truly understands and represents individuals. Our mark system consists of three elements: the Logomark, the Wordmark, and the Combination Mark.

Logomark

The Delphic Epsilon is our symbol – a distinctive mark that can stand alone in contexts where the brand is already established.

Wordmark

The Delphi wordmark uses our custom Pythia typeface. Always include the registered trademark symbol (®) when space permits.

Combination Mark

When using the logomark and wordmark together, maintain proper spacing: the gap between elements should be 0.5× the height of the logomark.

Use the dark logo on light backgrounds and the light logo on dark backgrounds.

• Use the logo in its original proportions
• Maintain clear space around the logo equal to the height of the epsilon
• Use the light logo on dark backgrounds and vice versa
• Stretch, distort, or rotate the logo
• Add effects like shadows, gradients, or outlines
• Place the logo on busy backgrounds that reduce legibility

Typography

Our typography system pairs three typefaces: Pythia for display, Inter for body text, and Geist Mono for code and metadata.

Pythia Type

Our in-house typeface, used for our wordmark. We use Pythia for headlines, the wordmark, and specific Delphi features such as profile names. It includes expanded iconography as glyphs within the typeface.

Pythia Type replaces the Apple logo glyph with the Delphi logomark  — press ⌥⇧K while typing to insert it.

Inter Variable

A classic sans-serif that's free and open source. We use Inter for body text, interface elements, and all long-form content. Its variable font capabilities allow for precise weight adjustments.

Geist Mono

Our monospace companion, used for code, keyboard shortcuts, and tabular figures — anywhere fixed-width alignment matters. It keeps technical content calm and legible without competing with Pythia or Inter.

• Use Pythia for headlines, the wordmark, and profile names
• Use Inter for body text, UI elements, and long-form content
• Use Geist Mono for code, shortcuts, and tabular numbers
• Use Pythia for body text or long paragraphs
• Mix other typefaces with our brand fonts
• Use weights outside of our defined scale
