During the fourth China International Import Expo, we specially designed a pavilion composed of gratings and multi-layered colors using the illusion of vision. This pavilion is exclusively dedicated to SHISEIDO and is named the "Colorful Pavilion." It serves as a significant project commemorating the 40th anniversary of SHISEIDO in China and celebrates the "colorful" 40 years that SHISEIDO and Chinese consumers have shared. Drawing inspiration from the origin of the "SHISEIDO" brand name and the concept of "Praise the virtues of the Earth, which nurtures new life and brings forth significant values." from the Book of Changes, we integrated the brand-specific colors of all brands under the SHISEIDO group into a seamless flow of colors. With the theme of infinite flow, we created the "Colorful Pavilion," where colors dynamically shift and intertwine with the movement of the viewer's gaze through a unique visual overlay across four spatial layers. This design has made the "Colorful Pavilion" one of the most dazzling projects at the fourth China International Import Expo.
