Poster and magazine colour scheme

I want to keep a similar colour scheme through out my magazine and poster, so my audience will know they are referring to the same film. I have chosen to use the colours green, blue, red, white and black as there are iconic sci fi colours. They remind people of space, galaxies, lasers and aliens. This will help my target audience understand the genre of the film my magazine and poster are advertising. Also these colours will make my magazine stand out from others as most magazines use very bright colours to try and grab attention and as my colours will not be as bright, my front cover will stick out more.
