In computer vision there is a well-known problem of estimating the color of the lighting. I worked on detecting the player's skin color for a recent computer game. We decided not to use an RGB camera for pretty much the same reason as seen in the strawberry illusion - the computer would see those strawberries as gray. An image with unknown lighting might look fine to a human but it's hard for a computer to estimate the actual color of objects without also seeing objects of known color, such as a color card.
