Oh man, after seeing Erine's swatches, they totally look like halves of the Sonic Chic blushes were used, like I thought so, when I first read the descriptions.
Moon River = Dainty
Love Rock = Pleasantry
Intenso = Gleeful (which I love btw though
)
Grand Duo = Gentle?? (I don't own this color)
And any of the browns could be like Love Joy or similar enough to not make purchasing one worth it if you have Love Joy already.
