supports-color reliably detects whether a TTY (teletypewriter) supports color. It examines environment variables like TERM and flags passed to Node.js to determine color support levels: basic (16 colors), ANSI 256 colors, or truecolor (16 million colors). This package is instrumental in allowing command-line applications to tailor their output for optimal user experience, ensuring accessibility and visual appeal across diverse terminal environments. It uses logic from many projects like chalk, and ansi-styles.
