Overview​

The atmos theme command allows you to customize the visual appearance of Atmos CLI output. Themes control:

  • Color schemes for tables, status messages, and command output
  • Syntax highlighting for code blocks and configuration examples
  • Markdown rendering styles for help text and documentation
  • UI element styling including borders, headers, and emphasis

Atmos includes a curated collection of themes optimized for both dark and light terminal backgrounds, with several recommended themes tested for optimal readability and accessibility.

Subcommands​

Quick Start​

Theme Configuration​

You can set a theme in two ways:

Environment Variable​

Set the ATMOS_THEME environment variable before running Atmos commands:

export ATMOS_THEME=dracula
atmos terraform plan

This is useful for testing themes or switching themes temporarily.

Configuration File​

Add the theme to your atmos.yaml configuration:

settings:
  terminal:
    theme: dracula

This makes the theme setting persistent across all Atmos commands.
