Sin City Analysis-editing

The first point of editing that I notice in Sin city is the emphasis on the woman.I can see this because the scenery around her is black and white, except for her red lipstick and red dress. The colour red is a representation of confidence and evil, so this could be a possible warning of what is to come.
In the first minute of the film there are 5 cuts,after all 5 cuts the woman is seen. This shows me that she will be a prominant character within the film. just after the first minute we see the woman smoking a cigerrete that was given to her by the man she is talking to. Even though the cigerrete is lit when we see an over the shoulder shot from behind the man of her smoking it it does not glow,this could be so that the audience does not get distracted by anything and are always focusing on her,we can also see that the lighter flame is also in black and white.
As i said before everything we see is black and white except the womans dress and her lips,this is emphasised by the cigerrete and the flame and also by the gun that the man pulls out.
When the titles begin these are also in black and white,the words are coloured red.
When the titles end the film is still in black and white.
to summerise the film is a black and white film but the colour red is the only colour that we see. This colour is only seen with the woman. This is to possibly emphasise a later role she may play that will envolve evil and death.
