Imagine a world in which the colors you see do not necessarily represent the correct ones. Imagine, when you approach a traffic light, you cannot tell what
color the light is. Imagine the colors of traffic lights changing from one block to the next one. Could you?
If you can’t, just go to your computer. In the world of visual computing, you cannot be sure what the colors will be. Even today. And today, the awareness
of computer professionals to color has grown orders of magnitude.
