.SH NAME
Color::Calc::WWW \- Simple calculations with colors for the WWW.
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 6
\&  use Color::Calc::WWW;
\&  my $background = \*(Aqgreen\*(Aq;
\&  print \*(Aqbackground: \*(Aq, color($background),\*(Aq;\*(Aq;
\&  print \*(Aqborder\-top: solid 1px \*(Aq, color_light($background),\*(Aq;\*(Aq;

.SH DESCRIPTION
.IX Header "DESCRIPTION"
The \f(CW\*(C`Color::Calc::WWW\*(C'\fR 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.
.PP
This module is nearly identical to using the following:
.PP
.Vb 1
\&  use Color::Calc(\*(AqColorScheme\*(Aq => \*(AqWWW\*(Aq, \*(AqOutputFormat\*(Aq => \*(Aqhtml\*(Aq);
.Ve
.PP
However, this module also makes the functions available when not imported:
.PP
.Vb 2
\&  use Color::Calc::WWW();               # don\*(Aqt import
\&  Color::Calc::WWW::color(\*(AqF00\*(Aq);
.Ve
.SH USAGE
.IX Header "USAGE"
By default, all functions are imported.
.PP
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.
