The appearance of this textile changes depending on the incident light and the observer’s position.
Foil threads with retroreflective beads and a thin interference layer are woven into the textile, showing interference colors corresponding to the optical length of the incident light’s angle.
Thus, the foil threads display a range of colors because of interference colors that change with the angle of incident light.
Additionally, the three-dimensional structure of Nishijin produces more intricate interference colors.
