Hailing from 1972 and currently streaming on the specialized horror service Shudder, All the Colors of the Dark  is a giallo,  a genre of Italian cinema that specialized in sensation lurid tales often centered on aspects of sex, sexual perversion, and violence. Part of the global exploitive cinema of the 1970s and 1980s, giallos  are colorful, have amazing photography, and bold art direction, the best of them are usually associated with the noted directors Mario Bava and Dario Argento. Though an Italian film All the Colors of the Dark  was filmed and set in England.

Jane (Edwige Fenech), while recovering from a car crash that injured her and killed her unborn baby, is tormented by terrifying visions of a knife-wielding attacker. The vision manifest most often when Jane and her boyfriend Richard (George Hilton) attempt to be sexually involved. Richard insists she needs vitamins, while her sister Barbara, who works for a psychiatrist presses for psychiatry. Jane’s neighbor, Mary, introduces Jane to a satanic coven and the events explode into debauchery, assault, and murder with Jane’s visions becoming apparently real as she loses connection with reality.

With plenty of blood and nudity All the Colors of the Dark is not a film for the young, sensitive, or easily offended. The final act of the movie ties things together with an explanation, but this, as with most giallos  in my opinion, is more a perfunctory move providing only the barest of rationales that allow the dream-like and nightmarish imagery to play out.  This sort of movie you do not watch for logical consistency or carefully interlocking plotting but rather for the surreal nature of the visuals and the emotional punch of the scenes. I find the style reminiscent of David Lynch albeit with a much more conventional approach.
