Themes & AppearanceNEW
Switch CLI color themes, auto-detect light/dark terminals, and run without color.
The Sophon CLI ships with four hand-tuned color themes plus an automatic monochrome mode. Themes shape the brand accents, syntax highlighting, and diff colors used across panels, tables, and the interactive chat REPL.
Themed visuals are part of the default experience — no opt-in needed. If you opt out of the enhanced UI with SOPHON_CLI_V2=0 (or "v2": false in ~/.sophon/config/cli.json), output falls back to plain console styling. See Configuration & Auth.
The themes
| Theme | Best for |
|---|---|
| indigo-core | The default — balanced indigo accents on a dark terminal |
| deep-void | OLED / true-black terminals; deeper surfaces, brighter brand |
| graphite | A muted, low-saturation look for long sessions |
| daylight | Light terminals; darker text and accents tuned for white backgrounds |
| no-color | Automatic monochrome — no ANSI colors at all |
Setting a theme
Choose a theme with the SOPHON_THEME environment variable:
SOPHON_THEME=deep-void sophon chatTo apply it to every session, export the variable from your shell profile (~/.bashrc, ~/.zshrc, or your PowerShell $PROFILE):
export SOPHON_THEME=deep-voidForce monochrome output for any reason (logging, pipes, accessibility) with the standard NO_COLOR convention:
NO_COLOR=1 sophon statusAutomatic detection
When you don't set a theme explicitly, the CLI picks one for you. Resolution happens in priority order:
NO_COLOR— if set (to any value), the monochrome theme wins and all color is stripped.SOPHON_THEME— an explicit theme name (indigo-core,deep-void,graphite,daylight).- Terminal background probe — if your terminal reports a light background (via
COLORFGBG), the CLI selects daylight automatically. indigo-core— the default fallback when nothing else applies.
So a light-background terminal that exports COLORFGBG gets readable colors out of the box, and a piped or NO_COLOR environment stays clean — without any configuration.
COLORFGBG is set by many terminal emulators (e.g. some xterm builds, rxvt). If yours doesn't report it, export SOPHON_THEME=daylight from your shell profile.
