This Perl module is a simple and convenient interface to the ANSI terminal escape sequences for color (from ECMA-48, also included in ISO 6429). The color sequences are provided in two forms, either as constants for each color or via a function that takes the names of colors and returns the appropriate escape codes or wraps them around the provided text. The non-color text style codes from ANSI X3.64 (bold, dark, underline, and reverse, for example), which were also included in ECMA-48 and ISO 6429, are also supported. Also supported are the extended colors used for sixteen-color and 256-color emulators. This module is very stable, and I've used it in a wide variety of applications. It has been included in the core Perl distribution starting with version 5.6.0, so you don't need to download and install it yourself unless you have an old version of Perl or need a newer version of the module than comes with your version of Perl. I continue to maintain it as a separate module, and the version included in Perl is resynced with mine before each release. The original module came out of a discussion in comp.lang.perl.misc and is a combination of two approaches, one with constants by Zenin and one with functions that I wrote. I offered to maintain a combined module that included both approaches.
