I apologize for the panel before last. Those guns look like crap, and not even consistent crap. I had a sudden attack of Stupid Fingers.
But I hope this strip fleshes out the deal with Penny in color. Though some bits of color are strictly stylistic there's good reason Penny appears in full color.
Only Hares can see the color, and only a few rabbits have it. If you've noticed you'll see that Ed and Wesson both have white eyes. Their glasses block out the color causing color rabbits to appear normal. They get an official name later in this chapter.
Pay attention and take notes. All of this will eventually come together.
Lastly next week's preview where guns don't look like inconsistent crap.
