If you have any suggestions for more color dictionaries to integrate, contact me.

METHODS

$dictionary = Color::Library->dictionary( <dictionary_id> )
    Returns a Color::Library::Dictionary object corresponding to <dictionary_id>

@dictionaries = Color::Library->dictionaries
@dictionaries = Color::Library->dictionaries( <dictionary_id>, <dictionary_id>, ... )
$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

$color = Color::Library->color( <query> )
    Returns a Color::Library::Color object found via <query>

    A query can be any of the following:

    color name
        A color name is like "blue" or "bleached-almond"

    color title
        A color title is like "Dark Green-Teal"

    color id
        A color id is in the form of <dictionary_id>:<color_name>, for example: "x11:azure1"

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>

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");

$color = Color::Library->colors
$color = Color::Library->colour
$color = Color::Library->colours
    All are aliases for the above color method

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.
