hello rover

One day the little rover looked up from it's path and saw the most amazing thing. A great blueness above. Like an insect flying into ones eye, you just can't miss it. The rover thought about the blueness. "I wonder why it's so blue?" "Would the blueness cause the ground to appear a different colour than if the sky were white?" "What is colour anyway?" So many questions the rover had running around it's brain. Of course, the rover had studied all the standard answers to those questions. But that didn't seem to explain satisfactorily how wonderful the world would look when illuminated by a giant big blue sky. The rover refocused on the path ahead and continued across the desert under the great blue dome.
