The colors on this US Flag are all wrong. To put the red, white and blue back into the stars and stripes, look directly at the false-color flag for 15 seconds. Use the handy timer below.
When the time is up, quickly look at the blank white areas of the screen. You see a ghostly image of the flag with correct colors!
After images always occur in their opposite, or complimentary color. In this case the opposite of orange is blue, the opposite of green is red, and the opposite of black is white.
