After watching a video at BellaSugar, it seems I made wrong assumptions regarding Ubangi.
Here is the video:

They used Ubangi as a base, then layered Outremer, Night Flight and Marie-Galante on top (and then the glitters).
Screencap from the video:
Therefore... Ubangi is in the top left corner.

That's Ubangi on the models' lids. Diane Kendall says they used it as a base, and the models don't seem to have anything layered on top (except maybe on the last picture).
