I've only got the one book on Venetian glassware - Vetri Veneziani dal Rinascimento all'Ottoscento: Colori e Transparenze - and colours such as yours pop up around the last half of the 19th century, but I can't see any vaguely similar shapes.
But the book is by no means exhaustive.
I wouldn't really like to hazard an opinion on them, as they're really not my field.
