NAME
       Graphics::Toolkit::Color::Manual::Cookbook - examples that solve
       practical issues

SYNOPSIS
       This manual page answers practical problems with multi line code
       examples and their detailed explanation with some added background
       knowledge.  This is complementary to the reference pages that contain
       only one line examples that showcase a single method or argument.

RECIPES
   How to convert color values?
       GTC has no dedicated converter methods in the style of rgb2hsl because
       it supports 33 color spaces, which would result in 33 * 32 = 1056
       methods.  GTC objects represent a color independent of a color space.
       That is why the constructor will accept colors defined in all supported
       spaces and the method values will give you a numeric output in the
       desired color space set by the argument in and many formats.  A
       conversion of an ordinary CSS color will therefore look like:

         use Graphics::Toolkit::Color qw/color/;
         my $okhsl = color('rgb(34, 56, 123)')->values( in => 'OKHSL', as => 'css_string');

   How to translate a CSS color name into values and back?
         my $color = color('CSS:blue');
         $color->name(from => 'CSS');

   How to get a split complementary palette?
         my @colors = $color->complement( steps => 3, tilt => 3.42 );
         my @colors = $color->complement( steps => 4, tilt => 1.585 );

   How to get a monochrome palette?
