Column Header Color with Text Filter

I have a grid, where the column headers have navy blue color. One of the column is having text filter. In that, where column header text is appearing, background in navy blue, but where the filter text box is appearing, the background is default theme color (sky blue). I want entire background to be navy blue. Please advise what should I do.

My code looks something like this:

myGrid.setHeader(“Name,Age”, null, [“background-color:#273A7F;color:white”,“background-color:#273A7F;color:white”]);
myGrid.attachHeader("#text_filter,#rspan)

Please, try to use:

myGrid.setHeader("Name,Age", null, ["background-color:#273A7F;color:white","background-color:#273A7F;color:white"]); myGrid.attachHeader("#text_filter,#rspan", ["background-color:#273A7F;color:white","background-color:#273A7F;color:white"])

That worked, thanks!
