Dropdown Menu

Hello,

We were wondering if you may be able to help us with the Following on our Primary Menu?

We have the header Background as Color #3f5678 with #ffffff Text.

When we Hover (On Desktop) or Select (On Mobile) we would like to have the Background colors reverse:

Background: #ffffff
Text: #3f5678
Plus/Minus Icons: #3f5678

Any help would be greatly appreciated!

Thanks so much in advance!
Greg
