Kepler-186f is the first Earth-size planet discovered in the habitable zone of another star – where liquid water could exist on the surface. If plant life did exist on Kepler-186f, leaves might be shades of red to generate energy from its cool, red star – very different than Earth's palette of greens under our yellow Sun. What tones will you pick to color Kepler-186f?
