One of the problems with many giallos is the unsatisfactory way they resolve the mystery the audience was plagued with. It is often either completeley predicatable or, in the other extreme, so completely unconnected to what was going on earlier to be meaningless. Tutti i colori del buio does not suffer from either problem, in fact the viewer is thoroughly misled about where the film is going.
The film is situated in England (mostly London), which was a rather fashionable location for Italian films of that period. This was probably not an ideal choice - in many ways the central characters remain unmistakably Latin, and some attempts to inject Englishness into the film have gone wrong. For example, Luciano Pigozzi's lawyer speaks a mixture of posh English and working-class English which sounds very weird - the whole cinema (in London) was laughing when he said "come to me office".
