Northern and Southern Lights to highlight the value of cold biomes

Bringing auroras to the night sky would make the game more alive, vibrant, and contemplative, perfect for players to simply sit back and appreciate the scenery from their bases. They could appear as waves Soft colors in the sky, varying in incredible gradients between blue and purple in some snow biomes, and green and orange in others (such as in the Taiga, giving it more prominence). The difference is that the player wouldn't need to be inside the biome to see the effect: Just like the Sun, the Moon, and the clouds, the aurora would be visible in the sky from a distance, wherever you are nearby..
