Both DVD covers of these two films include colour black, and the colour red. The femme fatale on The Killers DVD cover is wearing red lipstick (which is iconography from the film noir genre) and the title in the Double Indemnity is also in red. This shows that red and black are the dominant colours used in film noir.
As well as this, the femme fatale and the anti-hero characters are both featured on both DVDs. This shows that these two characters are typical and important for the film noir genre.
