PDFs in Obsidian

Hi every one I have been experimenting with PDF files in Obsidian and I have been having some problems, the first problem I'm facing is that I can't get to embed PDF in Obsidian unless I manually put the PDF in the folder I want, the second problem that I have is any PDF that I open in Obsidian (not in a note but in Obsidian native environment) is in black and white and not colored, I confirmed its because the style setting plugin that I use, I was looking for solution to fix this problems.

The only plugin I'm using for PDF is PDF++.

And I want to tank you all in advance.
