Fallshirmjager Camo Ardenns???

I believe they had the splinter pattern camou (looks geometric in design) and some were issued with reversible white parkas. Best to look at some war photos to see if they wore white during that particular battle - off hand I don't recall seeing this. The pea pattern ... if you mean spotted or dotted camou, that was only worn by the SS troops.

I know that but I mean is there any that are not complicated like the pea pattern or splinter cammo? so like the white or solied field grey....

There´s a book entitled 'Hitler´s sky warriors' which is about German paratroopers during the war.

My ordered kits arrived today, and I got a good idea from the box, but I need to know in Tamiya colors, what colors I should use?
