I looked at the picture again ... it's the Ivoire/Ivory color ...
Gosh, Ceejay, it looked too "cold" to me to be the ivoire... I checked Ivoire as well on Diabro (http://diabro.net/product_info.php/cPath/192_237/products_id/8779) and it looks a lot yellower. This looks almost like a pale, pale celery. Or maybe it's just that the pic taken was really bad. But why call it celadon then?!
You know what ... now that you mention it, Balenciaga did make a Whistle bag in a strange Celadon color, and the name that was used to describe it was "Celery"! Maybe this is the Celery color ???
