=head1 NAME
Color::Library - An easy-to-use and comprehensive named-color library
=head1 VERSION
version 0.021
=head1 SYNOPSIS
use Color::Library;
# Search for a sea blue color
my $seablue = Color::Library->color("seablue");
# Search for a grey73 in the 'svg' and 'x11' dictionaries only
my $grey73 = Color::Library->colour([qw/svg x11/] => "grey73");
# Find a bunch of colors at the same time
my ($red, $green, $blue) = Color::Library->colors(qw/red green blue/);
# Fetch the named color "aliceblue" from the SVG dictionary
my $color = Color::Library->SVG->color("aliceblue");
# Prints out "aliceblue is #ff08ff"
print $color->name, "is ", $color, "\n";
# Get a list of names in the svg dictionary
my @names = Color::Library->SVG->names;
# Get a list of colors in the x11 dictionary
my @colors = Color::Library->dictionary('x11')->colors;
=head1 DESCRIPTION
Color::Library is an easy-to-use and comprehensive named-color dictionary. Currently provides coverage for www (svg, html, css) colors, x11 colors, and more.
=head1 DICTIONARIES
The following dictionaries are available in this distribution:
Color::Library::Dictionary::SVG - Colors from the SVG specification
Color::Library::Dictionary::X11 - Colors for the X11 Window System (rgb.txt)
Color::Library::Dictionary::HTML - Colors from the HTML 4.0 specification
Color::Library::Dictionary::IE - Colors recognized by Internet Explorer
Color::Library::Dictionary::Mozilla - Colors recognized by Mozilla (ColorNames.txt)
Color::Library::Dictionary::Netscape - Colors recognized by Netscape
Color::Library::Dictionary::Windows - Colors from the Windows system palette
Color::Library::Dictionary::VACCC - VisiBone Anglo-Centric Color Code
Color::Library::Dictionary::NBS_ISCC - Centroids of the NBS/ISCC catalog
Color::Library::Dictionary::NBS_ISCC::A - Dye Colors
Color::Library::Dictionary::NBS_ISCC::B - Colour Terminology in Biology
Color::Library::Dictionary::NBS_ISCC::F - Colors; (for) Ready-Mixed Paints
Color::Library::Dictionary::NBS_ISCC::H - Horticultural Colour Charts
Color::Library::Dictionary::NBS_ISCC::M - Dictionary of Color
Color::Library::Dictionary::NBS_ISCC::P - Plochere Color System
Color::Library::Dictionary::NBS_ISCC::R - Color Standards and Color Nomenclature
Color::Library::Dictionary::NBS_ISCC::RC - Rock-Color Chart
Color::Library::Dictionary::NBS_ISCC::S - Postage-Stamp Color Names
Color::Library::Dictionary::NBS_ISCC::SC - Soil Color Charts
Color::Library::Dictionary::NBS_ISCC::TC - Standard Color Card of America
You can see a list of colors in any of these by reading their perldoc. For example:
perldoc Color::Library::Dictionary::VACCC
If you have any suggestions for more color dictionaries to integrate, contact me.
=head1 METHODS
=over 4
=item $dictionary = Color::Library->dictionary( <dictionary_id> )
Returns a Color::Library::Dictionary object corresponding to <dictionary_id>
=item @dictionaries = Color::Library->dictionaries
=item @dictionaries = Color::Library->dictionaries( <dictionary_id>, <dictionary_id>, ... )
=item $dictionaries = Color::Library->dictionaries( <dictionary_id>, <dictionary_id>, ... )
In list context, returns a list of Color::Library::Dictionary objects (for each <dictionary_id> passed in
In scalar context, returns a hash of Color::Library::Dictionary objects mapping a dictionary id to a dictionary
When called without arguments, the method will return all dictionaries
=item $color = Color::Library->color( <query> )
Returns a Color::Library::Color object found via <query>
A query can be any of the following:
=over 4
=item color name
A color name is like C<blue> or C<bleached-almond>
=item color title
A color title is like C<Dark Green-Teal>
=item color id
A color id is in the form of <dictionary_id>:<color_name>, for example: C<x11:azure1>
=back
=item color( <query>, <query>, ... )
In list context, returns a list of Color::Library::Color objects corresponding to each <query>
In scalar context, just returns the first <query>
=item color( <dictionaries>, <query>, ... )
If an array reference is passed as the first argument, then this indicates that the array is a list of dictionary ids to search
through (in order):
# Search in the svg and x11 dictionaries for a match
my $blue = Color::Library->color([qw/svg x11/], "blue");
# Will not find "aquamarine1" in the svg dictionary, so it will try the x11 dictionary
my $aquamarine1 = Color::Library->color([qw/svg x11/], "aquamarine1");
=item $color = Color::Library->colors
=item $color = Color::Library->colour
=item $color = Color::Library->colours
All are aliases for the above color method

=head1 ABOUT
This package was inspired by Graphics::ColorNames, and covers much of the same ground. However, I found the Graphics::ColorNames interface difficult to use. I also wanted to list colors directly in the perldoc, which this package does.
