System Colours

Description	The four main star colours
Updated	Prisms

This article is about the current version of System colours. For the Atlas Rises version, see System colours (Atlas).

System colours classify star systems based on colour.

Summary[ | ]

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[ | ]

Warp Reactor Required: Cadmium Drive
- Recipe requires Chromatic Metal
Unique Resource: Cadmium
Uncommon rare materials
95% are Uncharted systems, low chance for inhabited systems.
Look for Category K/M stars to identify them on the Galactic Map

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 Yellow Exotic — **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, but the most likely explanation is that the probabilities for Biome types of these colored stars (Red, Green, & Blue) do not change based on Galaxy type.

Due to the harsh galaxy missing, the speculation is that this galaxy type is like the norm galaxy, but with more storms.

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

Normal planets[ | ]

This is the table for normal planet probability:

System colours	Yellow			Red	Green	Blue
Galaxy Biome	Norm	Lush	Empty	All
Lush	2	4	1	1	1	1
Toxic	1	1	1	1	1	1
Scorched	1	1	1	1	1	1
Radioactive	1	1	1	1	1	1
Frozen	1	1	1	1	1	1
Barren	1	1	1	1	1	1
Dead	2	0.5	4	2	2	2
Weird	0	1	1	3	1	2
Red	0	0	0	1	0	0
Green	0	0	0	0	1	0
Blue	0	0	0	0	0	1
Swamp	0	0	0	0	0	0
Lava	0	0	0	0	0	0
All	0	0	0	0	0	0

Prime planets[ | ]

This is the table for prime planets, the planets that have been added with Origins:

System colours	Yellow			Red	Green	Blue
Galaxy Biome	Norm	Lush	Empty	All
Lush	2	4	1	1	1	1
Toxic	0.5	0.5	0.5	1	1	0.5
Scorched	1	1	1	1	1	1
Radioactive	0.5	0.5	0.5	0.5	0.5	0.5
Frozen	1	1	1	1	1	1
Barren	1	1	1	1	1	1
Dead	0.5	0.5	0.5	0.5	0.5	0.5
Weird	0	0.5	0	0.5	0.5	0.5
Red	0	1	1	3	0	0
Green	0	1	1	0	3	0
Blue	0	1	1	0	0	3
Swamp	1	1	1	0	2	1
Lava	1	1	1	2	0	1
All	0	0	0	0	0	0

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 colour and their class:

System	Color	Class	Faction	Planets	Moons
Galactica Neungs-Awes 3hahahas	Blue	06	Unavailable	5	0
RSS Iestrave VI	Yellow	E1f	Korvax	3	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.
- Exception: this indicator was not present during the Atlas Rises updates 1.30 through 1.37

Star Colour 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 Colour is consistent (at least generally) across all three game platforms:

Note: The different colours 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.
