Not sure I understand, as my footprints are both black both sides.
My Icarus one has a "Vango nameplate" in one corner, so this goes face up. My Kampa one just goes with the hem face down.
Not much help, sorry!
Although your footprint is not a thermal protection device, the idea of the shiny side on any such material is to reflect heat back from where it came from. So if the ground is cold - shiny side up.
If you ever camp on a volcano! - shiny side down.

Ive seen inbuilt groundsheets with silver up sometimes, down on others! lol
The thermal element to the equation could work both for and against I would think whichever side up. I genuinely wouldnt want to say which is best. I would tend to think on more of a purely practical level... which side is best able to cope with feet trampling over it, or best able to handle the odd bit of stone under it and the associated abrasion etc etc.
