说明
Terminal color is controlled through ANSI escape sequences, special character codes interpreted by terminal emulators to change text appearance. These sequences start with ESC (\\e, \\033, or \\x1b) followed by formatting codes. Colors enhance readability of command output, differentiate log levels, highlight errors, and improve user interfaces in terminal applications. Most modern terminals support 256 colors and true color (16 million colors). The tput command provides a portable way to generate escape sequences. Environment variables like TERM and NO_COLOR influence color support detection.
