Italian Giallo Horror

Since I have been asked to base the art created of Itallian Giallo Horror style I want to have a real look in to what it is and what connotations come with this genre. 

" Giallo (Italian pronunciation: [ˈdʒallo], plural gialli) is an Italian 20th-century genre of literature and film, which in Italian indicates crime fiction and mystery. In English, it has come to refer to a particular style of (typically Italian) murder mystery films which includes elements of horror fiction and eroticism (similar to the French fantastique genre). The word "giallo" is Italian for "yellow" and comes from a series of cheap paperback mystery novels with trademark yellow covers. " - Wikipedia (Giallo)

"Spaghetti thriller" is another phrase used for Italian produced Giallo films. These films are gripping thrillers with bloody, gory scenes and dramatic posters.
