Symbolism of the color white
Spoiler warning: Plot or ending details follow.
Each of the Hitman games has made use of the color white in some symbolic form. Up until Hitman: Contracts, 47's death was portrayed by him falling backwards in pain on a white background and bleeding heavily. Every game in the series demonstrated significant plot points with the color white; with the first three games with a white background, with the final game the white church in which 47 was dressed in white. Fans are uncertain as to the exact significance of this color; a walkthrough of the penultimate mission in Hitman 2: Silent Assassin where this color appeared as "a vision of heaven, and proof of betrayal", indirectly implying an omnipresent hope for 47's Catholic redemption. However, this opinion is let down by the simple fact that a large portion of the mandatory violence in the series has occurred in churches; in Hitman: Blood Money, 47 went so far as to murder an innocent priest. Others interpret the whiteness as a symbol for 47's isolation from the world, and solely occasional lapses into emotion when he is generally so completely detached. The argument for his isolation is strengthened by the fact that whenever another character has joined 47 in the whiteness for significant plot points they have been killed by him; Dr. Ort-Meyer, Sergei Zavorotko and No. 17 were all killed by 47 in white backgrounds. In the white church 47 killed everyone attending the funeral (with the exception of Diana; dressed in black with her hair dyed black where previously in Hitman: Contracts it was white). Also, in the case of Dr. Ort-Meyer and Sergei Zavarotko, it was not logic, practicality or monetary reward which motivated the violence; both were killed for very personal reasons.
Whatever else, it is certain that on some level the whiteness is metaphorical. This can be confirmed by the pivotal moment in 47's psychological growth, when he completed his Oedipal hit list by killing Dr. Ort-Meyer. In Hitman: Codename 47, 47 kills all of the No. 48's and then enters into a small antechamber into a laboratory which is a similar colour to the rest of the underground facility. Dr. Ort-Meyer approaches him in this antechamber; however, as soon 47 shoots him the antechamber disappears to be replaced with the white background in which 47 snaps Dr. Ort-Meyer's neck. When the events following Ort-Meyer's death are returned to in Hitman: Contracts, an opening cutscene shows 47 killing a No. 48 in an ordinary-looking room before entering into the white area in which he kills Dr. Ort-Meyer. Once this cutscene is finished 47 must leave this white room; attempting to return to it shows that the door in which 47 enters is mysteriously locked. In Hitman: Blood Money, in a brief flashback narrated by Alexander Leland Cayne (i.e. not directly following 47's perspective), this medical facility is shown as it truly is, with the room in which 47 kills Dr. Ort-Meyer appearing more or less the same as the antechamber from Hitman: Codename 47.
