Chromus is the one planet in this solar system that is composed of all the colors of the other planets.

 

The landscape is similar to a part of all the other planets: oceans, mountains, volcanoes, geysers, lush forests, farmlands and beautiful beaches.  The weather is always perfect, just like most of their people. 

 

The population is made up of descendants of those who have migrated from the other planets to the rainbow planet.
