UpThemes Framework : Afficher en Front End

Bonjour,
J'utilise le Framework UpThemes pour créer une page d'option personnalisée pour mon WordPress.
Dans la doc du site, ils expliquent comment afficher les option en back end, mais ils ne disent pas comment les afficher en Front end.
Voici ma page :

<?php
/**
 * Theme Colors and Images Settings Functions file
 * 
 * Below is an example of creating a new tab for your Theme Options page: */
$colors_images_tab = array(
    "name" => "colors_and_images",
    "title" => __("Colors and Images","upfw"),
    'sections' => array(
                    'color_scheme' => array(
                                      'name' => 'color_scheme',
                                      'title' => __( 'Color Scheme', 'upfw' ),
                                      'description' => __( 'Select your color scheme.','upfw' )
                    )
                )
);
register_theme_option_tab($colors_images_tab);

 // The following example shows you how to register theme options and assign them to tabs:
$options = array(
    'theme_color_scheme' => array(
                            "tab" => "colors_and_images",
                            "name" => "theme_color_scheme",
                            "title" => "Theme Color Scheme",
                            "description" => __( "Select a color scheme for your website", "example" ),
                            "section" => "color_scheme",
                            "since" => "1.0",
                            "id" => "color_scheme",
                            "type" => "select",
                            "default" => "light",
                            "valid_options" => array(
                                                "light" => array(
                                                            "name" => "light",
                                                            "title" => __( "Light", "example" )
                                                                 ),
                                                "dark" => array(
                                                "name" => "dark",
                                                "title" => __( "Dark", "example" )
                                                              )
                                                    )
                                                        ),
  "theme_footertext" => array(
                        "tab" => "colors_and_images",
                        "name" => "theme_footertext",
                        "title" => "Theme Footer Text",
                        "description" => __( "Enter text to be displayed in your footer", "example" ),
                        "section" => "color_scheme",
                        "since" => "1.0",
                        "id" => "color_scheme",
                        "type" => "text",
                        "default" => "Copyright 2012 UpThemes"
                      ),
  "font_color" => array(
                    "tab" => "colors_and_images",
                    "name" => "font_color",
                    "title" => "Font Color",
                    "description" => __( "Select a font color for your theme", "example" ),
                    "section" => "color_scheme",
                    "since" => "1.0",
                  "id" => "color_scheme",
                  "type" => "color",
                  "default" => "#ffffff"
                )
);
register_theme_options($options);

 /* The different types of options you can define are: text, color, image, select, list, multiple, textarea, page, pages, category, categories
 *
 */
?>

Les options sont bien là, elle s'affichent correctement dans le panel d'admin mais je ne sais pas comment les afficher. D'ailleurs je ne sais même pas si les options sont bien enregistrée ou pas dans La Base De Donnée.
Quelqu'un aurait-il déjà utiliser un FrameWork pour Options de Thèmes ?
