Crime/Thriller Titles

Gone Girl Opening Titles 

Here the font is very simple, it's all sans-serif and capital giving it a matter of fact feel reflective of the way crimes are solved. It is also slightly translucent connoting that there is more to the crime than we first see and it will ultimately be be very difficult to solve.
The screen changes from the picture of a girl to a black screen which reflects the title 'Gone Girl'.
The general colour palette is dark, blues and greys. The have connotations of sadness, tragedy, crime and 'wrong doing'. This sets the tone for the rest of the film.

The Girl with the Dragon Tattoo Opening Titles

Much like 'Gone Girl', these titles are very dark, almost all black which definitely connotes danger and death. Furthermore, the title is engulfed by a black liquid showing the all consuming darkness of the film - it sets a very clear, tense tone.
The text is sans-serif but odd looking, almost spiky and unpleasant to look at. This could be implying an unpleasant story line and foreshadow future discomfort later in the film.

Pulp Fiction Opening Titles

These titles, unlike the first two, have serif text and are actually quite bright. There is vibrant orange underneath a mucky yellow. This connotes that there is more to the characters than meets the eye and their actions are very unexpected.
This does not fit in with the general crime/thriller title as they are pleasant to look at and the text is serif - it's almost more commercial, less matter of fact than the rest of the titles I've looked at.

Fargo Opening Titles

These titles are more like 'Gone Girl', clean and matter of fact. This could reflect how it is based on true events and, again. how they are trying to solve a crime.
The colour choices are interesting as they do not conform with the standard crime/thriller colour scheme. Even 'Pulp Fiction' is on a black background but here the background is white, a colour usually associated with innocence, goodness and safety. It was actually used in the opening sequence to blend into snow white a car then drove out of which was effective editing. Therefore the white has a slight blue tint connoting there is sadness and tragedy in the story. It also makes it seem cold and unwelcoming which creates negative emotions within the audience before they've even seen where the car is driving.
The font is simple, capitalised and sans-serif, the general look for crime/thriller films.

Zodiac Opening Titles

This font is also capitalised and sans-serif suggesting that a something is being solved that involves factual information and careful planning and consideration.
However the strike through the 'O' is sinister and disrupts the order of the text creating a feeling of unease. This connotes how something strange is going on and how there's more to the story than there first initially seems.

Seven Opening Titles

These titles actually jump around on the screen in the title sequence so it was difficult to get a screenshot. They are sans-serif, much like most of the other titles but appear scratched on indicating that much of the case is yet to be solved, possibly the characters are faced with something they've never seen before.
The 'V' in the word is replaced with the number '7' in the titles indicating the importance of the number and how it will eventually lead to the pattern the murderer is following - the 7 deadly sins.
It also disrupts the flow of the text connoting how this case is different to all the others and is difficult to solve.
The words are on a black background, again setting a dark tone for the film.

The Bourne Identity Opening Titles

These titles are very simple, capitalised and sans-serif which could connote how the protagonist has lost all his memories and is only left with simple disjointed thoughts. This is also reflected through how the text is separate, not joined up. They are on a black background showing the underlying darkness of Bourne's story which we come to learn later in the series.
There is a slight blue tint shining behind the text. This has connotations of loneliness and sadness possibly relating to Bourne's history as an assassin but also symbolising how he is alone in a dangerous, frightening situation.
The almost futuristic very computerised look of the text reflects the technology used to try and find him and his background in the secret service.

Hostage Opening Titles

In this title sequence cast names appear on the side of buildings trough a city, this particular shot is a bird's eye view looking down between the buildings possibly showing how the characters search high and low for answers. 

The colour scheme is black and white, much like the other titles, but the background is not solid, there's things going on, possibly connoting chaos later in the film. The font is red so it stands out in the titles. Red has connotations of danger, pain and warning suggesting to the viewer that the film is about an unpleasant event that the hero has to stop or save. There are bits of black in the first few letters creating a darker feel to the picture showing us the severity of what happened. 

Overall, crime thrillers use:

-Sans-serif text

-Capitalised text

-Dark colours

-Solid backgrounds 

They are generally quite factual as they are about crimes but have a darker spin. Some have slightly different text like 'The Girl with the Dragon Tattoo' which I really like as it creates a real sense of unease.
