#41a1cfBlue accent for outlined action borders, linked labels, and lightweight interactive emphasis. Do not promote it to the primary CTA color
General Intelligence Company uses an editorial, almost literary visual language: a warm off-white canvas interrupted by hand-painted atmospheric illustrations (moonlit skylines, wildflower meadows) that do the emotional work, while the actual UI lives on clean white between these scenes. Typography carries the brand — a custom display serif (ppmondwest) speaks in a low, measured voice at 48–54px with tight -0.04em tracking, while a custom sans (af) handles everything utilitarian at 13–18px. Color is nearly absent: a warm parchment white, a soft green-gray border, and one vivid blue (#41a1cf) used only as an outlined action border. Components whisper — 4px and 8px radii, hairline 1px borders, subtle backdrop-blur on the navigation, no decorative shadows.
#41a1cfBlue accent for outlined action borders, linked labels, and lightweight interactive emphasis. Do not promote it to the primary CTA color
#0081c0Vivid blue used for a singular saturated card surface — the lone moment of pure color intensity, used sparingly as atmospheric punctuation
#fefffcPage canvas — warm off-white slightly creamier than pure white, gives the whole site its book-page atmosphere
#ffffffCard surfaces, section backgrounds, footer — the slightly cooler clean white used for elevated content areas
#f9faf7Input fields, subtle surface wash, nav fill — barely-perceptible off-white that reads as neutral
#171717Primary foreground token, strong body text where maximum contrast is needed
#2c2c2cHeadlines and key body text — softer than pure black, pairs with the warm canvas
#444141Secondary text, button text — the workhorse text tone for body copy and UI labels
#646464Muted helper text, descriptive copy, subdued UI
#b4b8b4Tertiary borders, disabled states, lightest neutral in the scale
#dee2deHairline borders on cards, buttons, and section dividers — green-tinted to harmonize with illustrations
#282834Near-black with a cool blue undertone — used for nav borders, icon strokes, and outlined actions; reads darker than its lightness suggests
#1f1f29Filled button background — a near-black with cool violet undertone, the only non-white filled surface in the system

Custom display serif for headlines and editorial copy — the voice of the brand. Tight -0.04em tracking at large sizes makes it feel set rather than typed; weight 400 even at 54px creates a confident, literary register rather than the 700-weight shouts common in tech. Liga features disabled.
Custom sans for all UI, body copy, navigation, buttons, and small headings — a quiet, neutral workhorse. Weight 500 is the default for interactive and label text; weight 400 for body. Slight negative tracking (-0.01em) keeps dense UI from feeling airy.

Contains a small sun/landscape icon, three text links (About, Writing, Careers) in af 15px weight 500, and a bordered 'Get Cofounder' CTA button. The blur and transparency let the illustrated hero show through softly.
8px border-radius, transparent background, 1px border in #41a1cf (Signal Blue), text in #41a1cf, af 15px weight 500, padding 5px 12px. The chromatic border is the entire visual identity of the button — no fill, no shadow. Arrow icon (→) inside a circle at the right edge.
8px border-radius, transparent background, 1px border in #282834 (Twilight), text in #282834, af 15px weight 500, padding 5px 12px. The neutral cousin of the primary CTA — used when a second action appears alongside.
8px border-radius, background #1f1f29 (Dusk), text white, border 1px in #282834, af 15px weight 500, padding 8px 16px. Used very sparingly — the only filled button in the system, appears in footer or high-emphasis contexts.
No background, no border, text in #444141 or #282834, af 16px weight 400, often with an arrow icon. The default for 'Get to know us' style links. Underlined version used inline within headings for cross-references.
Overlays the illustrated hero. 24px border-radius, semi-transparent background, backdrop-blur, generous padding (80px on the vivid blue variant), white or dark text depending on background. The frosted glass treatment ties the UI to the painted illustration.
12px border-radius, background #ffffff (Paper), 1px border in #dee2de (Mist), shadow rgba(0,0,0,0.08) 0px 1px 1px / 0px 4px 5px. Padding varies — 0px for media cards, 16px for text cards. The soft green-tinted border is the signature edge treatment.
Large format (often 1100000+ px area), 24px border-radius, vivid background color (#0081c0 Cerulean or painted landscape), generous internal padding 80-128px. These are the moments where color is allowed to exist — illustration-as-component.
16px border-radius, semi-transparent white background, subtle shadow rgba(0,0,0,0.05) 0px 1px 8px, padding 12px. Houses line-art diagrams (isolated agent squares, coordinator nodes) — the visual explanations are always inside this soft frame.
0px border-radius (flat edges), background #f9faf7 (Linen), text #444141 (Charcoal), border-bottom-only in #444141. No visible top/side borders — the input is defined by its fill color and a single bottom line, giving a paper-form feel.
White background, rounded corners, small font af 13px, inline text + Decline/Accept text buttons separated by a vertical divider. The minimal, text-first treatment is characteristic — no icons, no color, no urgency.
White background, large editorial statement in ppmondwest serif, small navigation links in af, generous vertical padding. The footer extends the literary feel — reading like the colophon of a book.

Full-bleed illustrated hero sections alternate with clean white content sections in a vertical rhythm. The hero is a 100vh painted illustration with a floating frosted-glass navigation pill at top-center and a glassmorphic overlay card at bottom-left containing the headline and CTA. Content sections are max-width 1200px centered, with generous vertical breathing room (64-96px). Headlines are left-aligned and large, often spanning 6-8 columns. Two-column layouts pair text with diagrams or illustrations. The diagram sections use a 6+6 split: explanatory text and figure caption on the left, line-art diagram in a soft-bordered card on the right. Navigation is a single floating pill — no sidebar, no mega-menu. Footer is a white band with a large editorial statement. The overall density is spacious: one idea per screen, never crowded.
Hand-painted digital illustrations carry the emotional narrative: a moonlit New York skyline with cherry blossom branches framing the composition, a dark wildflower meadow with golden poppies and purple flowers, a pixelated yellow-and-pink flower rendered in a low-resolution game-art style. The illustrations are painterly, not flat-vector — they have visible brush texture, atmospheric depth, and cinematic color grading (cool blues for night, warm greens for fields). All illustrations sit full-bleed or at 24px radius against the white canvas. No photography, no product screenshots, no abstract 3D. The pixelated flower is the one element that breaks the painted language — a deliberate contrast. Icons are minimal: a small sun-over-landscape glyph in the nav, simple line arrows in buttons.
