VERSION

       version 0.31

SYNOPSIS

           use Graphics::Color::RGB;

           my $color = Graphics::Color::RGB->new({
               red     => 1,
               blue    => .31,
               green   => .25,

DESCRIPTION

       Graphics::Color::RGB represents a Color in the sRGB color space.  Individual color
       channels are expressed as decimal values from 0 to 1, 0 being a lack of that color (or
       opaque in the case of alpha) and 1 being full color (or transparent in the case of alpha).
       If no options are provided then new instance of RGB are opaque white, (that is equivalent
       to red => 1, green => 1, blue => 1, alpha => 1).

       Convenience methods are supplied to convert to various string values.
