PDF Colors

Hi All,
I am using the latest free version of MarginNote in my Ipad (2018).
I select to import a PDF file, form my PC to the Ipad, using the Wifi import functionality.
When I open the PDF, the colors are not right. It looks like I am looking at a “negative” of the original.
Did anyone experience this?
Thanks for the help!

Hello, under the dark style is the opposite color, you can adjust it to another style.

Thanks very much for your quick reply ! That was the solution !
