Cookie Dough, as I mentioned a few days ago, looks a bit greenish, and Hazelnut Mousse more creamy.
On the left, the Mousse, and on the right side of the bead, the Dough. Here, you can easily see the greenish tone to the Dough.
And with the rods - Dough on the top, Mousse below. The difference is more obvious in the bead than on the rod - which look very similar.
Interesting colours. Definitely warrant more investigation.
