Hi @VAYALAS7, Create a Style for the Container and use the desired colour at the body tab.

Refer the style at your section where you need.

@VAYALAS7

• Create a CSS style sheet in your application.
• Add a classname for the control/layout 'testclass' in the properties configuration
• using this classname add background color like -

.testclass{

background-color:grey;

}

or 

• You can use Skin to give the specific color.
