Please guys - can you read the requests properly - ACTIVE colour.
You've added CSS to the hover and a href of the menu item.
I've tried to be very clear about changing the ACTIVE colour of the menu item headers. I've even outlined the issue that menu item headers do not add the active class in the Sphere template.
I don't see how any CSS you try will work unless there's a different class added to active menu items?
This is a development issue with the template (or possibly the helix system if that's running the menu module) - not adding the active class to menu item headers.
Here's the Active class in a normal menu item.

Here's NO Active class in a menu item header.

Please get this fixed.
