Minecraft wiki entry for Biome, associated text: In these biomes, it neither rains nor snows at all, but the sky still turns overcast during inclement weather. The foliage and grass is an olive tone, except badlands biomes, which have brown grass and the sky color is much brighter specially in deserts and badlands. Additionally, a snow golem spawned or brought into one of these biomes melts (takes heat damage) unless it has the Fire Resistance effect.
