dropdown color on logo, texts...

Hey,

My header starts off transparent with the different color themes. On the scroll it changes to a colour but I would like it to change to a white background with a black logo and black text, buttons and icons on the scroll.

And also: 

Right now my dropdown square under the text is placed to the right ( my text is centered under the dropdown text, so its fine) but I would like the the square to be centered as well, is it possible?

And I would like the dropdown to be transparent when it is fixed on the top of the side, but when scrolling down it should change to a white sqaure with black text ( so it will match the header when scrolling down)
