Background: The YouTube Theater is a venue where artists, creators, and fans come together to celebrate creativity and find inspiration. I led the development of a comprehensive style guide—from initial mood boards and foundational strategy to final lookbook and toolkit delivery for external partners, supporting all YouTube Theater marketing operations. In close collaboration with Hollywood Park designers, we crafted a unified identity system that merges the Hollywood Park and YouTube Theater brands into a cohesive visual experience tailored to the space, celebrating both creators and community.
