System colours classify star systems based on colour.


The colour of a star provides many clues as to what forms of life, resources, and other items appear on its planets.

Yellow systems[]

  • Warp Reactor Required: Hyperdrive
  • Unique Resource: Copper.
    • Note: these resources don't pertain to yellow stars only, they can be found in deposits formed only in yellow stars.
  • Sparse rare materials
  • All systems will be inhabited by a sentient race.
  • Look for Category F/G stars to identify them in the Galactic Map

Red systems[]

Green systems[]

  • Warp Reactor Required: Emeril Drive
    • Recipe requires Cadmium mined from Red Systems
  • Unique Resource: Emeril
  • Common rare materials
  • Average chance for uncharted and inhabited systems, low chance for Abandoned systems.
  • Look for Category E stars to identify them in the Galactic Map

Blue systems[]

  • Warp Reactor Required: Indium Drive
    • Recipe requires Emeril mined from Green systems
  • Unique Resource: Indium
  • Abundant rare materials
  • Average chance for uncharted and inhabited systems, low chance for abandoned systems.
  • Look for Category B/O stars to identify them on the Galactic Map

Biome probabilities[]

Likast 1 has Wire Cell type Exotic biome and located in a yellow star system (Visions)

When visiting a certain galaxy type, the probabilities of discovering various planet biomes are as follows. Meaning of the line "All" is not yet known.

The values in the table could be interpreted as per the following:

  • 4 - Very high chance
  • 3 - High chance
  • 2 - Normal chance
  • 1 - Low chance
  • 0 - Very low chance
System colours Yellow Green Blue Red
Empty Harsh Lush Norm All All All
Lush 1 2 4 2 0 0 1
Toxic 1 1 1 1 0 0 0
Scorched 1 1 0.5 1 0 1 1
Irradiated 1 1 0.5 1 2 1 0
Frozen 1 1 0 1 0.5 0 0
Barren 2 1 3 1 1 0 0
Dead 2 2 0 2 0.5 1 0

Red 0 0 2 0 1 1 0
Green 1 0 0 0 0.5 1 1
Blue 0 0 0 0 0 1 1
All 0 0 1 0 0 2 0.5

Convert Dead To Weird[]

Convert Dead To Weird is a property with a value of 0.5.

It was added in the Visions update that introduced new Weird (Exotic) biomes by converting previously existing Dead biomes.

Due to this change there is a higher chance to find these biomes, even in yellow star systems as well.

Colour Mismatch[]

Based on the information above, the following stars have an apparent mismatch between their color and their class:

System Color Class Faction Planets Moons
Hub11-15 Blue F5 Gek 6 0

Additional information[]

  • Current version of the game file related to the biome probabilities can be found here.
  • A star's colour is indicated by the first letter of the star's Spectral class. Much of the above information is courtesy of LoneSeeker777's post on Reddit.[1] Note that these are general results, and there may be exceptions.

Star Color Consistency Test[]

These images were taken of the same Star System found within each of the three game platforms. This is to show that Star Color is consistent (at least generally) across all three game platforms:

Note: The different colors within the galactic map images are because these images were not all taken from the exact same view point within the galaxy, some are looking towards the core and others are looking away, looking towards different galactic regions.
