Timeless Rainbow is a video artwork by Youngjun Chang released as part of Un-beauty series.

It presents an anonymous man questions his choreography, feeling trapped in a cycle of repetition. Rainbows cascade down his body like a vibrant cloak. The colour hues create a sharp contrast to the condensed memory of black ash beneath man's feet. It reflects Chang's idea about digital engagement. The man longs for a deeper connection beyond the hollow allure of digital engagement, yearning for the opulence of emotional richness in a space that is anything but empty.
