Paper for lang's orchid in ODS

[leung_wwy]

Hi - does anyone know what paper is used in lang's orchid in ODS and how he managed to get the middle top petal to be a deeper colour than the others?

It looks a bit like unryu but I am just guessing...

Thanks

Looks like Unryu, at least for the pink. I would venture a guess that it is an unryu sandwich, where Lang has through use of crease pattern or just simply knowing at some point which flaps turn into which petals, sandwiched the pink onto the white in only the places that are going to turn into that top petal and lower lip area....hope this helps...

Anyone else? the photo is on page 370...
