Color::Calc::WWW(3) Simple calculations with colors for the WWW.


use Color::Calc::WWW;
my $background = 'green';
print 'background: ', color($background),';';
print 'border-top: solid 1px ', color_light($background),';';
print 'border-bottom: solid 1px ', color_dark($background),';';
print 'color: ', color_contrast_bw($background),';';


The "Color::Calc::WWW" module implements simple calculations with RGB colors for the World Wide Web. This can be used to create a full color scheme from a few colors.

This module is nearly identical to using the following:

  use Color::Calc('ColorScheme' => 'WWW', 'OutputFormat' => 'html');

However, this module also makes the functions available when not imported:

  use Color::Calc::WWW();               # don't import


By default, all functions are imported.

All functions recognize all HTML color keywords (through Graphics::ColorNames::WWW) and output the results in WWW-compatible formats, i.e. as one of the 16 basic HTML keywords (see Graphics::ColorNames::WWW) or as #RRGGBB.

color, color_mix, ...
  See L<Color::Calc> for a list of available calculation functions.
