$black->toHEX(1) # #000000
$black->toRGB # rgb(0,0,0)

my $white = $black->lighten('100%');
my $black = $white->darken('100%');

my $transparent = $black->fadeout('100%');
$black = $transparent->fadein('100%');

...

use Colouring::In qw/lighten darken/;

my $white = lighten('#000', '100%');
my $black = darken('#fff', '100%');

my $transparent = fade('#fff', '0%');
my $transparent = fadeout('#fff', '100%');

my $colour = fadein('rgba(125,125,125,0'), '100%');

Instantiate

new

Instantiate an Colouring::In Object using a supported colour formated string or RGBA array reference.

my $colour = Colouring::In->new('hsla(0, 0%, 100%, 0.3)');
my $colour = Colouring::In->new([255, 255, 255, 0.3]);

rgb

Instantiate an Colouring::In Object opaque colour from decimal red, green and blue (RGB) values.

my $colour = Colouring::In->rgb(0, 0, 0);

rgba

Instantiate an Colouring::In Object transparent colour from decimal red, green, blue and alpha (RGBA) values.

my $colour = Colouring::In->rgb(0, 0, 0, 0.5);

hsl

Instantiate an Colouring::In Object opaque colour from hue, saturation and lightness (HSL) values.

my $colour = Colouring::In->hsl(0, 0%, 100%);

hsla

Instantiate an Colouring::In Object tranparent colour from hue, saturation, lightness and alpha (HSLA) values.

my $colour = Colouring::In->hsla(0, 0%, 100%, 1);

Methods

mix

Mix two colours.

my $mix = $colour->mix('rgb(255, 255, 255)', 'rgb(0, 0, 0)', $weight);

lighten

Increase the lightness of the colour.

my $lighter = $colour->lighten('50%');

darken

Decrease the lightness of the colour.

my $darken = $colour->darken('50%');

fade

Set the absolute opacity of the colour.

my $fade = $colour->fade('50%');

fadeout

Decrease the opacity of the colour.

my $fadeout = $colour->fadeout('10%');

fadein

Increase the opacity of the colour.

my $fadein = $colour->fadein('5%');

tint

Apply a tint to the colour.

my $tint = $colour->tint('rgb(255, 0, 0)');

my $tint = $colour->tint('rgb(255, 0, 0)', $weight);

shade

Apply a shade to the colour.

my $shade = $colour->shade('rgb(255, 0, 0)');

my $shade = $colour->shade('rgb(255, 0, 0)', $weight);

saturate

Increase the saturation of the colour.

my $saturate = $colour->saturate('rgb(255, 255, 255)', '50%');

desaturate

Decrease the saturation of a color.

my $desaturate = $colour->desaturate('rgb(255, 0, 0)', '50%');

greyscale

Remove all saturation from a color.

my $grey = $colour->greyscale('rgb(255, 0, 0)');

toCSS

Returns either an rgba or hex colour string based on whether the alpha value is set.

my $string = $colour->toCSS;

This method is called on stringification of a Colouring::In Object.

toRGB

Returns an opaque colour string from decimal red, green and blue (RGB) values.

my $string = $colour->toCSS;

toRGBA

Returns an transparent colour string from decimal red, green, blue and alpha (RGBA) values.

my $string = $colour->toRGBA;

toHEX

Returns an opaque colour string from decimal red, green and blue (RGB) values.

my $string = $colour->toHEX;

toHSL

Returns an opaque colour string from hue, saturation and lightness (HSL) values.

my $string = $colour->toHSL;

toHSV

Returns an opaque colour string from hue, saturation and value (HSV) values.

my $string = $colour->toHSV;

toTerm

Returns an opaque colour string from decimal red, green and blue (RGB) values valid for Term::ANSIColor foreground content.

my $string = $colour->toCSS;

toOnTerm

Returns an opaque colour string from decimal red, green and blue (RGB) values valid for Term::ANSIColor background content.

my $string = $colour->toCSS;

colour

Returns an array containeing the red, green and blue (RGB) values.

my $string = $colour->colour;
