I'm not sure why this isn't working. I got a hash that looks like this: 

        $hash= {
          'test_link_color' => '#31e500',
          'test_widget_header_color' => '#c6b989',
          'header_textcolor' => 'blank',
          'test_menu_color' => '#004d59',
          'test_widget_color' => '#eee3b7',
          'custom_logo' => 5,
          'test_headline_color' => '#7b0706',
          'custom_css_post_id' => -1,
          'header_image_data' => bless( {
                                          'height' => 250,
                                          'width' => 1140,
                                          'attachment_id' => 9,
                                        }, 'PHP::Serialization::Object
+::stdClass' ),
          'test_article_background_color' => '#ceddd2',
          'test_menu_text_color' => '#ffffff',
          'test_widget_title_color' => '#ffffff',
          'test_menu_hl_color' => '#a74d3d',
          'nav_menu_locations' => {
                                    'menu-1' => 2
                                  },
          'background_color' => 'ffffff',
          'test_text_color' => '#000000'
        };

I want to filter out all keys that aren't a color property, so I have: 

my %colors = map { $_ => %$hash{$_} } grep { $_ =~ /color$/ } keys %$h
+ash;

I'm getting a result with they key/values all mixed up: 

        %colors = (
          'ffffff' => 'test_text_color',
          'test_article_background_color' => 'test_article_background_
+color',
          'blank' => 'test_menu_color',
          'test_menu_text_color' => '#ffffff',
          'test_text_color' => '#000000',
          'background_color' => 'background_color',
          '#31e500' => 'test_widget_header_color',
          'test_widget_title_color' => 'test_widget_title_color',
          '#eee3b7' => 'test_headline_color',
          '#ceddd2' => 'test_menu_text_color',
          'test_menu_hl_color' => '#a74d3d',
          '#ffffff' => 'test_menu_hl_color',
          'test_link_color' => 'test_link_color',
          'test_widget_header_color' => '#c6b989',
          'test_widget_color' => 'test_widget_color',
          'test_headline_color' => '#7b0706',
          'header_textcolor' => 'header_textcolor',
          'test_menu_color' => '#004d59'
        );

I'm not sure what I'm missing here.
