Contemporary lighting technology has fully evolved into the precise algorithmic control of LEDs, where color temperature and wavelength become programmable digits. Yet, in an era when light required "filtering" through physical media, the color filter served as the indispensable palette in the hands of lighting designers.

Cold, stark LED tubes construct a rational, standardized foundation of modern illumination. The "square paper trash box"—a familiar sight in everyday Taiwanese life—symbolizes the final posture of an object stripped of its original utility. It resembles magnified pixels, appearing as if it were the ultimate deduction of optics. As modern light penetrates the medium of a bygone era, within the order of the three primary colors, what emerges is not merely color, but a solemn ritual of "sifting." This work attempts to retrieve discarded materials from the fissures of technological succession, re-examining the residual warmth and materiality of light.
