I did this already, they are waiting for kriesis response too

I did this via theme forest 5days ago waiting for your answer – no response yet. Could u please check my refund ticket?

Hi there, thanks for your answer but this is not the problem.
We have a transperent Logo in the header (png) and the menu color is white (#000).

Its fine when the user scrolls down, then the background of navigation changes to white and the font color to black.
Then the logo is visible (due to the white background).

But in initial state, the logo can’t be seen cause there is no white background.
So my idea was, that we have a second logo (with white colours) to be seen when there is no white background for navigation.
Can I send u screenshots in private mode?
