termenv is a Go library for safely adding colour and styling to terminal output. It detects the terminal’s capabilities and selects compatible ANSI colours and control sequences, avoiding the need to handle escape sequences and colour conversions directly.
The library supports applications running across terminals with different colour capabilities, automatically converting colours to the closest available alternative.
This is free and open source software.
