Chromatic

Chromatic worlds are the opposite end of the spectrum of Lightless spheres or Penumbra worlds: The ground is always so well lit that the word "night" is essentially meaningless here. Because of this, finding ores on these worlds is a very easy task.

Radiation is present in these worlds on the same extreme level as Irradiated planets. Chromatic Planets are mostly found orbiting blue stars.

A chromatic world at night:

Codex description
This unusual planet is Chromatic, with a radioactive atmosphere. Our scanners detect rare mineral deposits.

Notable Features
You can find a vast plethora of ores here, including Neptunium Ore, Thorium Ore, Zerchesium Ore, Prism Shards, as well as Gold, Iron, Titanium, Durasteel, Solarium, and Plutonium. In addition, one can find Crystals in the form of ores here as well. The chromatic dirt can be extracted for carbon, the chromatic rainbow sands can be extracted for silicon. As previously mentioned, the dirt is constantly glowing and is always completely visible, so locating these ores is extremely easy even at night.

Erchius Crystal subiomes are very common below the surface, and can be an extremely reliable source of fuel.

These planets are inhabited by Lumoths and Voltips.

The unique weapon Skittles can be found on Chromatic worlds.
