NAME
Acme::Colour::Fuzzy - give names to arbitrary RGB triplets
SYNOPSIS
# specify colour set, default is VACCC
my $fuzzy = Acme::Colour::Fuzzy->new( 'VACCC' );
# list of similar colours, sorted by similarity
my @approximations = $fuzzy->colour_approximations( $r, $g, $b, $count );
# made-up name for the colour
my $name = $fuzzy->colour_name( $r, $g, $b );
DESCRIPTION
This module uses sophisticated colour-distance metrics and some made-up computations to give a likely name to an arbitrary RGB triplet.
METHODS
new
my $fuzzy = Acme::Colour::Fuzzy->new( $colour_set );
Creates a new Acme::Colour::Fuzzy
object using the specified colour set. The coolour set can be any backend for Graphic::ColorNames
with 'VACCC' as default.
colour_approximations
my @approximations = $fuzzy->colour_approximations( $r, $g, $b, $count );
Returns a list of at most $count
colours similar to the given one. Each element of the list is an hash with the following structure:
{ name => 'Red', # name taken from Graphics::ColourNames
distance => 7.1234567,
rgb => [ 255, 0, 0 ],
}
colour_name
my $name = $fuzzy->colour_name( $r, $g, $b );
Makes up a colour name using the data computed by colour_approximations
.
