Controlling the color appearance of objects by optimizing the illumination spectrum
This addresses the problem of dynamic color control in fashion and entertainment, though it appears incremental as it builds on existing metamerism principles.
The researchers developed a lighting system that changes specific target colors while maintaining naturally white-appearing illumination by optimizing spectral power distribution to exploit metamerism. They demonstrated the system at Paris Fashion Week 2024, achieving impressive color transitions in dresses.
We have developed an innovative lighting system that changes specific target colors while keeping the lights appearing naturally white. By precisely controlling the spectral power distribution (SPD) of illumination and harnessing the unique phenomenon of metamerism, our system achieves unique color variations in ways you've never seen before. Our system calculates the optimal SPDs of illumination for given materials to intensively induce metamerism, and then synthesizes the illumination using various colors of LEDs. We successfully demonstrated the system's implementation at Paris Fashion Week 2024. As models step onto the stage, their dresses initiate a captivating transformation. Our system altering the colors of the dresses, showcasing an impressive transition from one stunning color to another.
