The official color palette for the Disney 100 Years of Wonder celebration, which took place throughout 2023 and early 2024, is centered around platinum and "iridescent" purple. These colors were chosen to represent a "once-in-a-lifetime" milestone, moving away from the "EARidescent" blue and gold used for Walt Disney World's 50th anniversary. Platinum was the primary metallic hue, symbolizing a century of strength and timelessness. You would see this reflected in the Disney100 merchandise, the decor on Sleeping Beauty Castle in Disneyland, and the special character costumes for Mickey and Minnie, which featured shimmering platinum fabric with purple accents. In 2026, while the official celebration has concluded, many of the platinum-themed souvenirs remain highly collectible. The aesthetic was designed to feel "regal yet modern," signaling a bridge between the traditional animation of the past century and the high-tech, digital future of the Disney brand as it enters its second century of storytelling.
