libcolor-ansi-util-perl - 0.165-1 main

Color::ANSI::Util provides routines for dealing with ANSI colors. The two
main functions are ansifg and ansibg. With those functions, you can specify
colors in RGB and let it output the correct ANSI color escape code according
to the color depth support of the terminal (whether 16-color, 256-color, or
24bit). There are other functions to convert RGB to ANSI in specific color
depths, or reverse functions to convert from ANSI to RGB codes.
