## Objective
Develop an original visual identity for my brief. Study the relationships between logo, type, color, and applications in this reference. Do not reproduce the referenced logo, name, distinctive artwork, or proprietary assets.

## Deliverables and checks
- Begin with the audience, positioning, personality, and required applications in my brief. Label assumptions.
- Explain two or three distinct identity directions before selecting one. Connect each decision to the brand's purpose.
- Define an original logo concept, wordmark and symbol relationships, typographic hierarchy, palette roles, and a consistent graphic system.
- Show how the system works on the relevant touchpoints: packaging, stationery, signage, social, or digital products.
- Draft practical guidelines for clear space, minimum size, background contrast, one-color and reversed marks, type usage, and layout. Validate proposed measurements in the actual artwork.
- Use appropriately licensed fonts and original or licensed imagery. Supply editable vector artwork when the tools support it; distinguish a concept from finished production files.
- Check small-size legibility, color accessibility for text, visual consistency, and print versus screen requirements. State what was reviewed and what still needs testing.
