Studio Blue
#5d8cd7Brand icon mark, decorative vector accent — cool blue against warm cream is the only chromatic tension in the marketing surface
Paper uses a warm-paper-studio language: a cream ivory canvas instead of white, calm monochrome typography in a custom display face, and a single cool blue accent that does almost no UI work. The two-tone headline (dark first line, mid-gray continuation) is the signature move — it treats the hero copy as a composition of weights rather than a single block. Surfaces sit flat on the page with one barely-there card shadow, borders are hairline, and the product feels like a printed notebook page under cool studio light. Most of the chromatic energy lives inside the product screenshot; the marketing surface around it stays restrained, near-achromatic, and grid-quiet.

Display and headline face — custom, wide stance, unusual light-to-medium weights (360 is whisper-thin). Carries the hero, the two-tone headline split, and large pull quotes. Tight tracking on display (-0.0200em at 64px) gives the type a composed, editorial feel
UI and body face — captions, button labels, nav, metadata, product chrome. Tight negative tracking on small sizes (-0.0100em at 12–14px) keeps dense UI legible
Code, file paths, version labels, tiny metadata. Loose positive tracking (+0.0150em to +0.0160em) at small sizes gives the mono a calm, terminal-like cadence

Transparent background, #181818 text, no border, Inter 14px weight 500, trailing arrow glyph (→) at 6px gap. Used for 'open Paper in the browser →' and other soft CTAs.
Inter 14px weight 400, #181818 text, 8px horizontal padding, no underline. 'downloads' is set in weight 500 as the active endpoint. Right-aligned cluster: 'sign up' in weight 400, 'downloads →' in weight 500.
Word 'Paper' in Inter 16px weight 600, #181818, preceded by a 14×14 #5d8cd7 rounded-square mark. The blue mark is the only saturated color in the header.
Matter weight 400 at 64px / 48px, split across two visual weights: first line in #181818, continuation lines in #83837 at the same size. Tracking -1.28px at 64px, -0.96px at 48px. Line height 1.00–1.14 — the lines stack tight, almost overlapping, for a composed editorial feel.
Inter 12px weight 500, #909090, often lowercase ('used in production by designers at', 'open alpha'). Optional 8px gap to the heading below.
Matter 18px weight 400, #666666, line-height 1.75, max-width ~56ch. No drop-cap, no bold inline emphasis — the tone is calm and expository.
White (#fcfcf9) surface, 8px radius, 32px padding around the app chrome, elevated with the three-layer card shadow. Contains traffic-light dots top-left, a sidebar of file names, and a right-side properties panel — all rendered as flat product UI inside the card.
Single row or two-row grid of customer logos, Pewter (#83837e) monochrome, 40–48px tall, 32–40px gap, centered. No dividers, no card wrapping. Eyebrow 'used in production by designers at' centered above.
Rounded panel with 8px radius, 12–24px padding, #fcfcf9 background, hairline #d7d7d6 border. Body in Paper Mono 11–12px weight 400. File paths and code keywords colored with brand blue (#5d8cd7), comment lines in #909090. No syntax-highlight rainbow — palette stays near-monochrome.
#fcfcf9 background, 1px #d7d7d6 border, 8px radius, 24–32px padding. Used when the product card would feel too heavy — text-only groupings, plan summaries, simple feature blocks.
Subtle thin-line isometric grid in #d7d7d6, drawn at ~20% opacity, anchored to the upper-right corner of the hero and select sections. Never full-bleed, always clipped to a triangular wedge. Provides spatial depth without adding color.

Shadows are used sparingly and only for one purpose: making the product screenshot and a few floating tool panels feel lifted off the page. Marketing cards, logos, and content blocks stay flat — they rely on the cream canvas, hairline borders, and white surface contrast to define themselves. No decorative drop shadows on headings or icons.

Centered max-width container at 1200px with comfortable side gutters on a full-bleed Bone Canvas. The hero is a left-aligned text block (eyebrow → two-tone headline → lead → button pair) with the product screenshot card centered below, slightly wider than the text column. Subsequent sections are centered single-column with eyebrow + two-tone heading + lead + content block, separated by 96px vertical gaps. Logo cloud sits as a centered band between hero and the first product section. The page uses a consistent rhythm: eyebrow → headline → lead → visual or content, never asymmetric or magazine-style. Navigation is a flat top bar with left-aligned logo and right-aligned CTA cluster; no sticky shadow, no mega-menu.
Almost no marketing photography. The single hero visual is a product screenshot of the Paper app itself, presented inside a white card with the three-layer shadow. Customer logos appear as flat monochrome wordmarks in a centered cloud. A faint isometric line grid in #d7d7d6 sits in the upper-right corner of the hero and repeats on select sections, providing spatial depth without color. Iconography (in the product UI) is line-based at ~1.5px stroke, monochrome, using Pewter and Iron.
**Quick Color Reference** - page background: #efefe4 (Bone Canvas) - card surface: #fcfcf9 (Paper White) or #ffffff (Bright Card) - text primary: #181818 (Ink) - text secondary: #83837e (Slate) or #666666 (Iron) - border / hairline: #d7d7d6 (Stone) - brand accent: #5d8cd7 (Studio Blue) — icons and code only, never buttons - primary action: #181818 (filled action) **3 Example Component Prompts** 1. *Hero section on Bone Canvas (#efefe4).* Two-tone headline: first line 'design incredible' in Matter weight 400 at 64px, color #181818, letter-spacing -1.28px; second line 'the connected canvas for teams shipping with agents' in same Matter 64px weight 400, color #83837e, line-height 1.0. Lead paragraph: Matter 18px weight 400, #666666, line-height 1.75, max-width 56ch. Button row: filled 'download Paper' — #181818 background, #fcfcf9 text, Inter 14px weight 500, 4px radius, 6px 14px padding. Ghost 'open Paper in the browser →' — transparent, #181818 text, Inter 14px weight 500, trailing arrow. 2. *Product screenshot card.* White #fcfcf9 surface, 8px radius, 32px padding around the app chrome, elevated with the three-layer card shadow (rgba(0,0,0,0.12) 0 4px 10px, 0 2px 4px -1px, 0 0px 4px -1px). Traffic-light dots top-left in #c1c1c0, sidebar in #909090, main canvas white. Right panel uses #f3f3f4 inputs with 4px radius. 3. *Logo cloud band.* Centered eyebrow 'used in production by designers at' in Inter 12px weight 500, #909090. Below, a centered grid of customer wordmarks in #83837e, 40px tall, 40px gap, single row or 2-row wrap. No card wrapper, no dividers, no per-logo backgrounds.
The headline is a two-line composition at the same Matter size: line 1 in #181818 weight 400, line 2 in #83837e weight 400, both at 64px (display) or 48px (heading). Tracking tightens with size (-1.28px at 64px, -0.96px at 48px). Line-height 1.0–1.14 makes the lines almost touch. Never bold, never italic, never a different font. This is the single most recognizable type move in the system.
Three layers stack: Bone Canvas (#efefe4) for the page, Paper White (#fcfcf9) for cards, Bright Card (#ffffff) for the highest-elevation product chrome. Hairline #d7d7d6 borders replace shadows on every marketing surface; the three-layer shadow is reserved for the product screenshot and one or two floating panels. Stone (#d7d7d6) and Smoke (#c1c1c0) are the only two border colors; never use a chromatic stroke.
