You know that old saying 'The pen is mightier than the sword'? Well how about 'the humble pencil is more powerful than a trained militia man if there are enough of them'? It might not roll off the tongue as easily, but it certainly seems to be true seeing as the gunman in the middle appears to be petrified of them.
The emphasis on color - both in the title of the piece and the various shades of pencil - is interesting and probably relevant. Maybe it's there to tell us that a world of many colors is better than one that's black and white. Maybe the point is that when people from all walks of life get together, they can overthrow tyranny. Maybe there's something more profound going on. Or maybe they're just pencils. What do you think?
