Imagine a world where the sky changes colors throughout the day, not just at sunrise and sunset. Morning starts with a soft purple hue, morphing into a bright blue by midday, and transitions into shades of green and orange by the evening. This phenomenon is observed on a planet with a unique atmospheric composition, allowing for these vibrant and unusual color changes. Visualize an expansive landscape beneath this sky, featuring a diverse ecosystem with bioluminescent plants and creatures adapted to this dynamic environment.
