The silica particles swept along by HD 189773b's harsh winds may form glass, and could even be responsible for the planet's azure color. TrES-2b, on the other hand, appears blacker than both coal and black acrylic paint. Scientists aren't entirely sure why the planet reflects less than 1% of the light that hits it, but theorize that chemicals in its atmosphere might absorb the light.
