Breathable roofing membrane silly question

[cwesty1]

silly question but which way up should my breathable felt go?
the label says coloured side up, it has a black slightly shinier side and a white holey side. it makes sense to me that the shinier side is more water resistant, whereas the porous looking side lets the moisture through.
i was expecting a this side up mark or something.
silly question but not as silly as wasting it and having to relay it all.
its a daltex roofTX if thats makes any difference.

Coloured side up. If it's on a roll you can't really get it wrong, it goes one way.
