Plasmate Brand Guide

"The living information, the plasmate, replicates itself - not through information or in information - but as information." -- Philip K. Dick, VALIS (1981)


Origin Story

The name Plasmate comes from Philip K. Dick's novel VALIS, where the plasmate is described as "living information" - an energy form that crosses between realities, transforms raw matter into structured intelligence, and replicates itself through contact with human consciousness.

This is exactly what Plasmate the browser engine does: it transforms the raw, chaotic HTML of the web into a Semantic Object Model - living, structured information that AI agents can understand, reason about, and act upon.

Plasma is the fourth state of matter. Agents are the fourth state of the web.

State Matter Web
1st Solid Static HTML
2nd Liquid Dynamic (JavaScript)
3rd Gas Real-time (WebSockets)
4th Plasma Agentic (SOM)

The "mate" suffix carries double meaning: a companion (your agent's browser companion) and the act of bonding (the plasmate "crossbands" with the agent, just as Dick described it bonding with human consciousness).


Brand Personality

Pioneer. We are building the Netscape of agentic browsers. The first to reject CDP and DOM as the interface between agents and the web.

Precise. This is an engine, not a wrapper. Every design decision reflects engineering discipline.

Open. Apache 2.0. The standard belongs to everyone. The brand should feel institutional enough to trust, not corporate enough to fear.

Alive. The plasmate is living information. The brand should feel energetic, luminous, present - never cold or sterile.


Color System

Philosophy

Plasma in nature is not one color. It is determined by the gas being ionized and the energy level of the excitation. Lightning is blue-white (nitrogen ionization at extreme temperature). Neon is amber-red. Solar corona is golden-white. The Plasmate palette draws from these real plasma emission colors.

No purple. No gradients. Flat, confident, scientific.

Primary Palette

Name Hex RGB Usage
Plasma White #F0EDE8 240, 237, 232 Backgrounds, body text areas. Warm white - not blue-white, not stark. Like the afterglow of an ionized field.
Core Black #0D0D0D 13, 13, 13 Primary text, dark backgrounds, terminal UI. Near-black with warmth.
Ember #E8853A 232, 133, 58 Primary brand color. The color of neon plasma - ionized gas at mid-energy. Used for the wordmark, primary CTAs, key accents.

Secondary Palette

Name Hex RGB Usage
Arc #3D8FD4 61, 143, 212 Secondary accent. The color of an electric arc - nitrogen plasma at high energy. Used for links, interactive states, code highlights.
Ion #D4C5A0 212, 197, 160 Tertiary. Warm sand/parchment tone. Backgrounds, cards, subtle dividers. The color of low-energy plasma glow.
Ash #6B6560 107, 101, 96 Muted text, captions, borders. Warm gray - the residue after plasma discharge.
Corona #F5C842 245, 200, 66 Highlight/attention only. The solar corona. Use sparingly for badges, warnings, "new" tags.

Dark Mode

Name Hex Usage
Void #111110 Dark background
Deep #1A1918 Cards, elevated surfaces
Smoke #2A2825 Borders, dividers
Dim #8A8480 Muted text in dark mode

Usage Rules

  1. Ember is the signature. When you see that warm orange on a dark field, you should think Plasmate. It should appear on every page, but not dominate.
  2. Arc is functional. Blue is for clickable things, focused states, and code. It is not decorative.
  3. Never use gradients. Flat color only. A gradient says "startup trying to look cool." A flat field of Ember on Core Black says "we built a browser engine."
  4. Corona is rare. It exists for moments of delight or urgency. If everything is golden, nothing is.
  5. White space is structural. Plasmate design uses generous whitespace. The content breathes.

Typography

Philosophy

Plasmate is infrastructure. The typography should feel engineered, not designed. We avoid Inter (ubiquitous to the point of invisibility), geometric sans-serifs that feel like SaaS dashboards, and anything with "startup energy."

Pixie Dust: The Particle System

Concept

The "pixie dust" is Plasmate's signature visual texture. It represents ionized particles - the fundamental unit of plasma. When matter transitions to the plasma state, atoms lose electrons and become a field of charged particles. This is what we visualize.

Implementation

Dot Field - A sparse, randomized grid of small circles (2-4px) at varying opacities (0.08-0.25) placed on dark backgrounds. The dots are always Ember (#E8853A) or Plasma White (#F0EDE8).

Rules:
- Dots are circular, never other shapes
- Size range: 2px to 4px diameter
- Opacity range: 0.08 to 0.25 (barely visible to faintly present)
- Density: sparse. Think starfield, not confetti.
- Distribution: pseudo-random with clustering bias toward edges
- Never animate on marketing pages (respect user motion preferences)
- On interactive surfaces (demos, playground): subtle drift at 0.1px/frame

Emission Lines - Thin horizontal or vertical lines (1px, Ember at 0.12 opacity) that suggest spectral emission lines from plasma discharge. Used as section dividers or background texture on hero sections.

Rules:
- Always 1px width
- Always Ember color at low opacity (0.08-0.15)
- Horizontal preferred; vertical only in sidebar contexts
- Spacing: irregular, clustered in groups of 2-4 with large gaps between
- Never more than 5-7 lines visible at once

Ionization Border - A subtle particle scatter effect along the edges of cards or containers. Small dots (1-2px) that appear to be dispersing from the edge of a surface. Suggests matter transitioning states at the boundary.

Rules:
- Only on key interactive cards (not every card)
- Particles scatter outward from the card edge
- 8-15 particles per edge
- Fade to 0 opacity within 20px of the card edge
- Use on: hero cards, feature highlights, the "SOM output" preview

Where to Use Pixie Dust

Context Technique Density
Hero background (dark) Dot field + emission lines Medium
Documentation None None - docs are clean
Code examples Subtle dot field behind code block Very low
Marketing cards Ionization border on hover Low
CLI / terminal screenshots Emission lines as scan lines Very low
404 / empty states Dense dot field (the void) High
Loading states Converging dot animation Medium

The Mark

The Plasmate mark is a stylized "P" whose vertical stroke disperses into particles at the top - matter transitioning into plasma. The letter form is geometric, drawn from Space Grotesk's proportions but simplified for icon use.

The dispersion effect at the top of the P is the brand's pixie dust rendered at mark scale: 5-8 small circles breaking away from the letterform, decreasing in size and opacity as they scatter upward and rightward.

Lockup Variants

Variant Usage
Full lockup Mark + "PLASMATE" wordmark (Space Grotesk SemiBold, uppercase, 0.06em tracking)
Compact Mark + "plasmate" wordmark (Space Grotesk Medium, lowercase)
Icon only The P mark alone. For favicons, app icons, social avatars.

Color Variants

Context Mark Wordmark Background
Primary (dark bg) Ember Plasma White Core Black / Void
Primary (light bg) Ember Core Black Plasma White
Monochrome (dark bg) Plasma White Plasma White Core Black
Monochrome (light bg) Core Black Core Black Plasma White

Clear Space

Minimum clear space around the full lockup: the width of the "P" mark on all sides. For the icon only: half the mark width.

Voice and Tone

Writing Principles

Be direct. "Plasmate compiles HTML into a Semantic Object Model." Not "Plasmate leverages cutting-edge AI to revolutionize how agents interact with the web."

Be specific. "10.4x compression on Wikipedia. 4ms per page." Not "blazing fast performance."

Be honest about scope. "v0.1 does not execute JavaScript dynamically" is better than silence. Open source trust is built on honesty.

Use the metaphor sparingly. The plasma/fourth-state metaphor is powerful in introductions and keynotes. In documentation, just be clear.

Naming Conventions

Thing Name Style
The product Plasmate Capital P, no "the"
The output format SOM (Semantic Object Model) Acronym, always capitalized
The protocol AWP (Agent Web Protocol) Acronym, always capitalized
The CLI commands plasmate fetch, plasmate serve Monospace, lowercase
The organization Plasmate Labs Two words, both capitalized
Element IDs e_a1b2c3d4e5f6 Monospace, always with e_ prefix
Session IDs s_abc123 Monospace, always with s_ prefix
