New Crater Blues — The blue appearance is due to the intense blast of the impact moving around dust on the surface. That dust is usually light-toned and reddish in color compared to what’s beneath it. When you remove the dust, you’re left with a dark spot that can sometimes be blue in comparison to the redder surroundings. These features are prominent only around young impacts, because all the old craters get covered with dust again over time.
