Yeah, basically you print the escape character (either \e or \033, I prefer the latter because I'm used to it and \e isn't actually standard C - although as far as I know it is widely supported), an opening square bracket ('['), numbers separated by semicolons and the letter 'm' (other letters are used for other types of escape codes).
To get back to the default, you must use '0' as the number. If several numbers are specified they will be executed in the order they appear, thus if two incompatible options are set (like green and red at the same time), the last one will be effective. You can prefix all your options with a '0' like "\033[0;<your options here>m", in case some of them are already set.
Don't forget to print a "\033[0m" at the end if you don't want the rest of your output to be messed.

Hi,

locale::codes::currency
Locale::Codes::Currency(3) User Contributed Perl Documentation Locale::Codes::Currency(3)NAME
Locale::Codes::Currency - standard codes for currency identification
SYNOPSIS
use Locale::Codes::Currency;
$curr = code2currency('usd'); # $curr gets 'US Dollar'
$code = currency2code('Euro'); # $code gets 'eur'
@codes = all_currency_codes();
@names = all_currency_names();
DESCRIPTION
The "Locale::Codes::Currency" module provides access to standard codes used for identifying currencies and funds, such as those defined in
ISO 4217.
Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 4217
three-letter codes will be used.
SUPPORTED CODE SETS
There are several different code sets you can use for identifying currencies. A code set may be specified using either a name, or a
constant that is automatically exported by this module.
For example, the two are equivalent:
$curr = code2currency('usd','alpha');
$curr = code2currency('usd',LOCALE_CURR_ALPHA);
The codesets currently supported are:
alpha, LOCALE_CURR_ALPHA
This is a set of three-letter (uppercase) codes from ISO 4217 such as EUR for Euro.
Two of the codes specified by the standard (XTS which is reserved for testing purposes and XXX which is for transactions where no
currency is involved) are omitted.
This is the default code set.
num, LOCALE_CURR_NUMERIC
This is the set of three-digit numeric codes from ISO 4217.
ROUTINES

These routines are all documented in the Locale::Codes::API man page.
