Brand Archetype System
Pre-composed aesthetic archetype defaults that jumpstart brand design work. Each archetype bundles color tendencies, type pairings, layout patterns, voice samples, and imagery direction for a recognizable aesthetic family. Stack-agnostic. Tool-agnostic.
This is a starting-point library, not a methodology library. The agent applies archetype defaults to a specific brief; the archetypes themselves provide anchor points, not endpoints.
When to use
The user wants a starting point rather than designing from first principles
The user references a brand or aesthetic family they want to design near
Need to converge faster from many directions to one
The user wants vertical-typical defaults (for example fintech consumer, B2B developer tools)
The user wants to test what a brief would look like in a different archetype
When NOT to use
The user wants pure methodology guidance (use brand-identity)
The user is in early ideation needing positioning territories (use brand-ideation)
Defining voice for an existing brand (use brand-voice)
Documenting a finished brand (use brand-style-guide)
How this composes with other skills
This skill works upstream of brand-identity (provides starting defaults that brand-identity refines into a finished system) and parallel to creative-direction (archetypes can be located by position on the 4 creative-direction axes).
Typical flow when this skill is invoked:
User provides a brief or references a target archetype
Agent picks the most relevant core archetype, or composes from 2 adjacent archetypes
Agent adapts the archetype's defaults to the brief (color tokens shift, type swaps to vertical-appropriate fonts, voice samples rewrite for the brand)
Agent flags adaptation choices made
Direct verbatim copying of an archetype's default palette into a new brand is a failure mode. Archetypes constrain the design space; the brief specifies the point within that space.
The framework: 12 core archetypes plus 18 vertical applications
Design or evaluate a brand visual identity system covering logo, color, typography, imagery direction, iconography, and motion principles. Use this skill whenever the user wants to design a logo, build a visual identity, define brand colors, choose brand typography, develop iconography, plan brand imagery, or evaluate an existing identity for cohesion.
