Copy PDF to Paint.net black tus blue

I used the snipping tool to copy a table from a PDF and pasted it into paint.net.

On zooming in the border is a solid black line and the numbers/text are multicolored blue/brown/yellow so it looks black (but fuzzy) when you zoom out and you see the colors when zoomed all the way in. Does this have to do with layers from the PDF, or the way text is handled, it is baffling to me that the line and text from the same snip have such a contrast in clarity.

(I checked and the original PDF is solid black)

Is snipping tool converting the colors or is it paint.net, or something else? What would be the next step in figuring out what's causing it?
(The hoped for solution would provide less "fuzzy" numbers after pasting.)
