=head1 NAME
Graphics::Color::YIQ - YIQ color space
=head1 VERSION
version 0.31
=head1 SYNOPSIS
use Graphics::Color::YIQ;
my $color = Graphics::Color::YIQ->new({
luminance => 0.5,
in_phase => .5,
quadrature => .25,
});
=head1 DESCRIPTION
Graphics::Color::YIQ represents a Color in an YIQ color space.
=head1 DISCLAIMER
I couldn't find clear information on the bounds of each value, so at the
moment there are none.
=head1 ATTRIBUTES
=head2 luminance
=head2 y
Set/Get the luminance component of this Color.
=head2 in_phase
=head2 i
Set/Get the in_phase component of this Color.
=head2 quadrature
=head2 q
Set/Get the quadrature component of this Color.
=head2 name
Get the name of this color. Only valid if the color was created by name.
=head2 not_equal_to
The opposite of equal_to.
=head1 METHODS
=head2 as_string
Get a string version of this Color in the form of
LUMINANCE,IN-PHASE,QUADRATURE
=head2 as_array
Get the YIQ values as an array
=head2 equal_to
Compares this color to the provided one. Returns 1 if true, else 0;
