**Version:** 2.0 (October 2026)  
**Selected Direction:** Proposal #1 from v3 Lookbook ([seb_labs_styles_v3.pdf](/brand/seb_labs_styles_v3.pdf))  
**CSS Tokens:** [design-tokens.css](/brand/design-tokens.css)  
**Applied In:** [pitch_deck.html](/brand/pitch_deck.html) & [seb_labs_seed_pitch_deck.pdf](/downloads/seb_labs_seed_pitch_deck.pdf)

## 1. Visual Philosophy & Art Lineage (Zero Red)

Instead of generic Silicon Valley dark-mode neon or Western red-folkloric clichés, **Seb Labs** draws its identity from the jewel-toned mathematical and artistic heritage of **Mikhail Vrubel** (*The Swan Princess*, *Demon Seated*), **Ural Malachite stonework**, **Rostov Finift pearl enamel**, and **Byzantine gold mosaic geometry**—fused with the probability theory lineage of **Kolmogorov and Markov**.

- **Core Visual Principle:** *Less text, more geometric infographics.* Every slide and web view combines luminous **Finift Pearl (`#F4F3EE`)** surfaces with deep **Vrubel Lapis (`#0E172A` $\to$ `#1E1B4B`)** monolith panels, **Ural Malachite (`#0D9488`)** winning vectors, and **Byzantine Mosaic Gold (`#C59B27`)** rules.

## 2. Color Architecture

| Token | Hex | Material Inspiration | Functional Role |
| :--- | :---: | :--- | :--- |
| `--bg-canvas` | `#F4F3EE` | **Rostov Finift Pearl Enamel** | Primary slide & page canvas |
| `--bg-surface` | `#FFFFFF` | **Imperial Porcelain** | Infographic cards, chart beds & tables |
| `--bg-lapis` | `#0E172A` | **Vrubel Midnight Lapis** | High-contrast monolith blocks, headers & dark telemetry |
| `--bg-indigo` | `#1E1B4B` | **Twilight Ultramarine** | Gradient partner for Lapis blocks |
| `--signal-malachite` | `#0D9488` | **Ural Cut Malachite** | Primary winning metric, `Seb-9B-v2` bars & argmax choice |
| `--signal-gold` | `#C59B27` | **Byzantine Mosaic Gold** | `Seb-9B-Fin` quant highlights, Northstar badges & borders |
| `--signal-indigo` | `#312E81` | **Northern Indigo** | `NVFP4` speed, hardware & 3D robotics telemetry |
| `--signal-amethyst` | `#6D597A` | **Smoky Amethyst** | Competitor bottlenecks & collapses (`0.0%` Clef-flash, `-11.1%` Sonnet) |

## 3. Signature Symbol, Mascot & Infographic Elements

1. **The Official Mascot & App Icon — *Kopyttse* (Серебряное Копытце, The Ural Silver-Hoof Fawn):**
   - **Why It Is 100% Unique in AI & Quant:** While OpenAI, Anthropic, and xAI use monochrome abstract swirls/slashes and Meta/DeepSeek/Sakana use a Llama, Whale, or Red Origami Fish, no AI or quantitative lab in the world uses the **Ural Silver-Hoof Fawn (*Kopyttse*)** from Pavel Bazhov's 1938 Ural folklore—where every stamp of the fawn's right front silver hoof sparks faceted green **Malachite & Chrysolite crystals** out of the snow.
   - **Mathematical Anatomy:**
     - **Decision-Graph Antlers ($G = (V, E)$):** Smooth Golden-Ratio ($\varphi = 1.618$) Bezier branches terminating in 6 glowing calibrated probability leaf nodes (`#2DD4BF` and `#E5B842`).
     - **Crown Argmax Crystal:** A levitating faceted Ural Malachite diamond (`#14B8A6`) between the antlers representing the winning calibrated decision (`argmax_i p_i`).
     - **Simplex Forehead Constellation ($\Delta^2$):** Three golden vertices on the forehead above gentle, expressive dark-lapis eyes with specular starlight catchlights.
   - **Production SVG Assets:**
     - [kopyttse_icon.svg](/assets/kopyttse_icon.svg) — Primary 512×512 App Icon & Oracle Bust Emblem.
     - [kopyttse_favicon.svg](/assets/kopyttse_favicon.svg) — Crisp 16px–64px Favicon, Header Badge & CLI Stamp.
     - [kopyttse_mascot_full.svg](/assets/kopyttse_mascot_full.svg) — Full-body action mascot stamping its Silver Hoof on the $\Delta^{K-1}$ probability simplex.
     - [seb_labs_kopyttse_brand_kit.pdf](/downloads/seb_labs_kopyttse_brand_kit.pdf) — 2-page Icon & Working Mascot System Spec Sheet (including 4 interactive product states: *Argmax Lock*, *21.7ms NVFP4 Reflex*, *Causal Guard*, and *System-2 Handoff*).
2. **The Malachite-Lapis-Gold Mosaic Border (`.malachite-border`):** A `7px` top and bottom geometric ribbon alternating Vrubel Lapis (`#0E172A`), Ural Malachite (`#0D9488`), Mosaic Gold (`#C59B27`), and Finift Pearl (`#F4F3EE`).
3. **Infographic-First Layout Rule:**
   - Maximum **1 headline + 1 short subtitle sentence** per slide.
   - **75%+ of every slide** is dedicated to bespoke SVG diagrams, diverging forest plots, quadrant scatter charts, impulse timelines, and visual gauges.
