Use a private variable to store you shortcode values:

class newelement extends WPBakeryShortCode {
    private $atts; 
    # Construct ----------------
    function __construct() {
        add_action( 'init', [ $this, 'elementMapping' ] );
        add_shortcode( 'element_Shortcode', [ $this, 'elementShortcode' ] );
        add_action( 'wp_enqueue_scripts', [ $this, 'elementCss' ]);
    }
    # Fields -------------------
    public function elementMapping() {
        if ( !defined( 'WPB_VC_VERSION' ) ) {
            return;
        }
        vc_map(
            [
                "base"              => "elementShortcode",
                "params" => [
                    [
                        "type" => "colorpicker",
                        "param_name" => "elementcolor"
                    ],
                ],
            ]
        );
    }
    # Output Code ---------------------------------
    public function elementShortcode () {
        $atts = shortcode_atts([
            "elementcolor" => "",
        ], $atts);
        $this->atts = $atts;
        extract($atts);
        ob_start();
        ?>

        <?php
        $output = ob_get_contents();
        ob_end_clean();
        return $output;
    }
    # css ---------------------------------
    public function elementCss() {

        $elementcolor = $this->atts["elementcolor"];

        $css = "
                 .element{ color: {$elementcolor} ;}
        ";
        wp_add_inline_style( 'main', $css);
     }
    }

No value of var_dump($elementcolor); is Null – mark Nov 22 '17 at 12:46 — mark, Nov 22 '17 at 12:46
what about var_dump($this->atts)? – madalinivascu Nov 22 '17 at 12:52 — madalinivascu, Nov 22 '17 at 12:52
