Character costume ideas

For my groups thriller opening I have a few ideas to contribute in the area of costume. The two characters have to show they have a connection, but the costume must also hint at their moral allegiance. Due to the conventions of the thriller genre, and indeed most genres, I suggest that the benevolent character should wear lighter clothing, and the malevolent one dark. This is due to dark clothing having connotations of evil, and lighter colours, generally having more positive connotations, alhtough this can change due to the particular colour, it's shade, or in which situation it is used.

The female character, Emily Gates, could wear a long coat (a light colour, such as yellow or light blue), a scarf (perhaps contrasting with the coat, perhaps dark colour to connect her to other character Josh), and gloves. Her being wrapped up as if in cold weather could symbolise her protecting herself from the outside world, and not wanting to be reminded of the loss of Joshua Moore.

Joshua Moore, the male bad character, should probably wear darker clothing, to make him appear more sinister in the dark, and to tell the audience of his part in the whole film. Plain clothes would probably be more appropriate, as this would show he is essentially a "normal" person. We may wish him to have something on his person to connect him to Emily Gates.
