 Think about, like, walking through the forest. You might not know what every different cluster of trees is, but the little subtleties in the greens and the shapes tell you, hey, this species, this plant is different than the other one. And so you can start seeing subtle differences simply by looking at color. And where we have this beautiful new mission come in is this brilliant fleet of Earth-observing systems NASA and others have had for years. They only measure two greens. They only measure two blues.
