kendo ui - How to change filter icon color or filter icon when column is filtered -

I've added filters: The grid of the right grid is properly filtered.

What do I want when the filter icon is clicked, then fill in the filter icon with a different color or change the color for the filter icon, so that the column filter icon can be clicked on.

Please tell it how.
