This is the movie poster for a new Leonardo Dicaprio and Martin Scorsese film that comes out on Christmas 2013. The color palette consists mainly of blue and yellow which are primary colors. There are accents of red which complete a triadic combination.
The hues that were chosen have a rich value and are complimented by several neutrals including browns, blacks, a little gray, and white. The general color palette does not include any other color outside of the triadic combination with the exception of a deep purple and soft pink. These are not distracting at all.
The overall impact of the colors is intense, but the use of deeper values makes it more sophisticated and less child-like.
