AnthraciteBRAND GUIDE

THE PATENT OFFICE · v0.1

A database platform,
drawn to spec.

This is the working reference for Anthracite's visual system, the parts and the whole on one page, so you can judge the direction before any real page is built. Everything below is live: real type, real components, real contrast.

01

In context

The system composed into the blocks a visitor would actually meet.

MASTHEAD
AnthraciteStart a database

Three engines.
One control plane.

Managed Valkey, Postgres, and OpenSearch, provisioned and operated from one place. No clusters to babysit, no command line to learn.

RESILIENCE

Automatic failover

A standby is promoted in under 30 seconds when the primary stops responding. No paging, no manual cutover.

Scale without downtimeFIG. 3

ELASTICITY

Scale without downtime

Resize compute and storage, or add read replicas, while the database keeps serving. Changes apply on the next health check.

Continuous backupsFIG. 4

DURABILITY

Continuous backups

Every write streams to object storage. Restore to any second in the retention window, into a fresh instance.

IN-MEMORY

Valkey

A Redis-compatible in-memory store for caching, sessions, queues, and rate limits. Sub-millisecond reads, with persistence when you want durability.

Color

A monochrome press, with two inks spent on purpose. Each chip carries its real WCAG ratio.

Primary

Burnt Orange--orange · #E1542Aoklch(64% .185 42)

Action and signature. The one CTA, the active engine, write nodes. Capped at ≤10% of any screen.

3.29:1 on paper · AA Large
Orange Deep--orange-deep · #AF421Eoklch(52% .155 40)

The only orange allowed as text or small marks on paper, because it clears 4.5:1.

4.99:1 on paper · AA

Secondary

Cobalt Blue--blue · #2A66C9oklch(56% .155 256)

Structure and state: diagram wiring, read nodes, and every focus ring.

4.71:1 on paper · AA
Blue Deep--blue-deep · #1B52ABoklch(48% .145 258)

Blue as text on paper: links and inline references.

6.36:1 on paper · AA

Neutral

Ink--ink · #16181Doklch(20% .012 264)

Every headline, word, line weight, and border. The brand's black.

15.29:1 on paper · AA
Muted Ink--muted · #4A4E56oklch(42% .012 264)

Secondary text, captions, labels. Never set body text lighter than this.

7.19:1 on paper · AA
Cool Paper--paper · #ECEEF2oklch(96.5% .006 255)

The page. A cool blueprint off-white, tinted toward blue, never warm cream.

15.29:1 ink on this · AA
Surface--surface · #FBFCFDoklch(99% .002 255)

Cards, inputs, and panels that lift a half-step off the paper.

17.29:1 ink on this · AA
Faint Line--line-faint · #D8DBE2oklch(88% .006 255)

The only divider lighter than ink, for low-emphasis separators.

Doctrine

The rules that keep the system from drifting back into slop.

The Rationed-Ink Rulecolor
Orange covers ≤10% of any screen. Its scarcity is the point; a page where orange is everywhere has spent the only loud voice on nothing.
The Two-Inks Rulecolor
Orange is action, blue is structure. They never swap jobs and never blend into a gradient.
The Cool-Paper Rulecolor
The background is #ECEEF2, cool and blueprint-toned. Warm cream, sand, and beige are forbidden.
The Mono-Is-Data Ruletype
Martian Mono carries numbers, codes, and labels. It never decorates prose, and it never fakes a terminal prompt. There is no CLI.
The Width-As-Voice Ruletype
The wide Archivo cut is for Display and Headline only. Body text stays at normal width.
The Ink-Not-Shadow Ruleelevation
Surfaces are flat at rest. Depth is line weight, halftone, and the hard Print-Lift offset. Soft glows are forbidden except on floating overlays.
The Engraving Ruleimagery
Illustrations are ink line art with halftone shading and isometric geometry. No flat blobs, no gradient meshes, no stock photography.

Do

  • Spend orange on the single action that matters most.
  • Set every page on cool blueprint-paper and carry structure in ink.
  • Use wide Archivo for display, Martian Mono for every number and label.
  • Draw depth with halftone line work and the hard 3px Print-Lift.
  • Keep focus rings cobalt blue, so focus never reads as hover.

Don't

  • Become the gray-on-gray cloud console this brand fights.
  • Drift into display-serif editorial restraint.
  • Use crypto / web3 neon: purple gradients, glow, hexagons.
  • Fake a CLI. There is no command line.
  • Set body text in bright orange or in the expanded Archivo width.
