Major Type of gas giant world.

The temperatures of these worlds range around -123 degrees Celsius, allowing for the formation of ammonia ice crystals stained by complex condensates of carbon and sulfur, which are constantly being formed by solar radiation. Because of this, the typical color of these worlds is yellow-brown, while banding occurs in the atmosphere due to high rotational rates, although that banding's visibility may be obscured by a uniform upper atmospheric haze. Typical albedos range around 0.57.
