The background color of the container is used for shutters by default with applied opacity. You can set a custom color for all elements, including the shutters, that use the container's background color. Use the RangeSelector's containerBackgroundColor configuration property to do this. To set a custom color for shutters only, use the shutter's color property directly.
This option supports the following colors:
