Building a Brand Graphic System for the AI Era

Triphollic, Yeogieottae's community service, carried out a new visual branding project to solve the graphic fragmentation problem that arises as the brand grows. The existing method of sharing design assets had limitations in that interpretations could vary from worker to worker, and a lot of resources were consumed each time for design review and communication.

To solve this, Triphollic went beyond a simple design guide and built the , which allows anyone to generate graphics in the same style. The core idea is to share the language (Prompt) that creates the graphics, instead of delivering the graphic outputs themselves.

The build process was as follows:

• Feature analysis: Trained ChatGPT and Gemini on existing graphics to extract features
• Element structuring: Defined graphic characteristics as three elements — Shape, Style, and Rendering
• Prompt optimization: Completed a structured prompt that compensates for edge cases and reliably reproduces a stable tone and manner through repeated generation testing

Through this project, Triphollic integrated AI generation rules together with logo, color, and font into a single systematic visual system, securing scalability for the brand experience.
