how to pass values from controller to layout file in yii2

Question

I'm trying to pass a variable value from controller to my main.php layout file but i keep getting error Undefined variable: contentWrapperBackground. below is my code

controller
public function actionList()
{

   $contentWrapperBackground = "ff4400;";
    $contentBackground = "3c8dbc;";
    return $this->render('list', [

         'contentWrapperBackground' =>$contentWrapperBackground,
         'contentBackground' => $contentBackground,

    ]);
}

and in my layout file like this

<div class="content-wrapper" style="background-color:#<?=$contentWrapperBackground?>">
    <!-- Content Header (Page header) -->


    <!-- Main content -->
    <section class="content" style="background-color:#<?=$contentBackground?>">

but i always get error Undefined variable: contentWrapperBackground. I'm trying to change the background color of for different pages. any help on this, and am also open to another idea on how to make this work thanks

don't use session for this!

Simple solution:

class Controller extends \yii\web\Controller
{
    $public $contentWrapperBackground;

    $public $contentBackground;
}

class YourController extends Controller
{
    public function actionList()
    {

         $this->contentWrapperBackground = "ff4400;";
         $this->contentBackground = "3c8dbc;";
         return $this->render('list', []);
    }
}

in your main layout

<div class="content-wrapper" style="background-color:#<?=Yii::$app->controller->contentWrapperBackground?>">

or another option

<div class="content-wrapper" style="background-color:#<?=$this->context->contentWrapperBackground?>">

you can set param in controller

Yii::$app->view->params['paramName'] = 'data';

get data in layout

$this->params['paramName'];
