Brand Identity
Design or evaluate the visual artifacts that express a brand: logo system, color, typography, imagery, iconography, and motion. Stack-agnostic. Tool-agnostic.
This skill assumes a brand direction is already approved (positioning, mood, name). If not, run brand-ideation first.
When to use
Designing a logo system
Defining a brand color palette
Choosing brand typography
Developing iconography or illustration style
Defining imagery direction (photography, illustration)
Establishing motion principles
Auditing an existing identity for cohesion or gaps
When NOT to use
Brand direction is not yet defined (use brand-ideation)
Documenting a finished system (use brand-style-guide)
Defining voice and tone (use brand-voice)
Building UI components from an existing brand (use design-standards or design-system)
Required inputs
The brand name and approved positioning
The mood direction (from ideation, or supplied as references)
