Is Pluto angry rather than embarassed at no longer being a planet?

Despite what the first New Horizons photo of Pluto appears to show, Pluto may be turning red with rage rather than pale with embarrassment at the news that it's no longer a planet.

At least that's what the chemistry says. And Hubble observations support it.

Meanwhile, here's the north pole of another dwarf planet, Ceres- which was also briefly considered a planet before we realized that it was simply the largest of a new class of objects called "asteroids." The Ceres story was in many ways a parallel to what happened when we realized that Pluto was merely a large- if typical- Kuiper Belt Object. The photo was taken by NASA's Dawn spacecraft.
