US FlagAn optical illusion is a visually perceived image that is deceptive or misleading.
Look at the center of the image for about 30 seconds. Then quickly shift your gaze to somewhere with a white background. You should see an afterimage of the US flag with the correct colors! This happens because your eye reverses the colors in afterimages.
