Cherry Soda is a color scheme that includes red, ivory, and antique gold. These colors have been used together in items before, but it didn't have an official name until the release of Noble Fleur de Reve and Cherry St BerBarry on February 17th, 2017. Hints of black/offblack might appear in a pose, but are not required. Presumably the name comes from the red/ivory gradient that might appear in some poses, giving it a "fizzy" aesthetic.
Not to be confused with Librarian, which is primarily brown with a red/umber gradient.
If combined with pine green, then it's called Festive.
