After-image: It is not uncommon if you have been staring at a computer screen for periods of time to see a purple after-image when you close your eyes. Similarly, if you have been outside and looking in the direction of the sun that you will see an after-image. Almost any light source can generate such an after-image and the after image will be brighter with brighter lights and longer viewing times.
