Color Codes are shipboard codes used to identify the level of risk associated with navigating various space areas.

Description (Specifications)[edit]

Maps of the Charted Space usually reference the color codes of the known areas.

  • Crews can thus know what to expect from them.
  • The color code of an area may change over time, including temporarily, although this is unusual.

History & Background (Dossier)[edit]
