Does cardboard reflect or absorb UV present in indirect sunlight?

 

Given the yellowish colour of that card, I would say it will absorb UV .
If it was white card (or maybe blue) I'd expect it to reflect it.
The problem is that you can't see UV so it's hard to tell

The inside of the box because the outside has boxes of different colors

Indirect sunlight  ?

I asked because any indirect sunlight must be reflected off something.

As a consequence indirect sunlight may contain reduced, greatly reduced or even on UV.

None of that box will reflect UV well.

I was referring to the color of the inner part of the box because all the cardboard boxes I own have the same internal color but it varies in the external colors so the UV reflects, is it abbreviated by the box? what happens?
