Color changing illusion

Access since May 26, 2008


"Two blue rings"

The inner ring appears to contract while the outer one appears to expand (optimized Fraser-Wilcox illusion). Moreover, the rings appear to rotate in the opposite directions when observers approach or move away from the image fixating at the center (Rotating Ouchi illusion). Furthermore, the inner ring appears to be more pale-bluish when observers approach the image fixating at the center, while the outer ring appears to be more pale-bluish when observers move away from the image. This image thus gives three different illusions.

"Into the sky"

The surround appears to be red when observers approach the figure while fixating at the center. In addition, the surround appears to move away and to rotate when observers approach the figure while fixating at the center

"Heat"

The rings appear to be red when observers approach the figure while fixating at the center, whereas they appear to be blue when observers move away from the figure while fixating at the center. For both cases, the rings appear to rotate in the different directions.
