Well, since the only photos of the rover preparing to roll are in black & white, it seems that NASA has prepared a color one for us to 'ooh & aaahh' at. The photo is actually from a practice run here on earth. The rover is ready to move, & is going to have to take an alternate route from the 'straight-off' approach originally planned. This change is due to the fact that one of the airbags is blocking the original path.
