I've never heard of it, but a postcard is floating around for it on the internet. It's not in the color stories either, but maybe somebody could mention it?
I remember Lightful line came out by itself, and this collection only contains skincare products.
So..in my opinion, I think this "White on White" maynot have anything to do with Lightful.
I just sent a whole bunch of pic for color stories to the "main office" on a lot of what may be missing on color stories. Hopefully they will post them for all of you to see.
