text color and background color don't work on floating-tools

[jianghongfei]

This is how floating-tools configured:

        CKEDITOR.config.floatingtools = 'Basic';
        CKEDITOR.config.floatingtools_Basic =
        [
            ['Styles', 'Font', 'FontSize'], '/', ['Bold', 'Italic', 'Underline', 'Strike', '-', 'TextColor', 'BGColor', '-', 'Link', 'Unlink']
        ];

but Textcolor and BGColor button, don't work
