I have chosen to research school colours as a way to settle on a colour scheme for my poster, this will give me an insight into which colours are good to experiment with, rather than me having no direction.
"Most competitive teams keep two sets of uniforms, with one emphasizing the primary color and the other emphasizing the secondary color. In some sports, such as American Football, the primary color is emphasized on home uniforms, while uniforms for other sports, notably basketball, use the secondary or a neutral color at home. This is done to avoid confusing the two schools' colors. In addition, various groups that generate support for athletic teams, including cheerleaders and marching bands, wear uniforms with the colors of their school."
This gives a description into school colours and why they are important, specifically American colours.
Here are a range of official colours used in certain school uniforms.
There appears to be an abundance of royals blues and surprisingly, shocking pinks, I wouldn't have initially expected this. I think that these colours used on my movie poster would set the wrong tone to what the film's genre was and the tone of the film, shocking pink especially.
Lime green stands out and is rather neutral in the grand scheme of things.
Here shows combinations of colours, green is used a lot and seems rather effective, Green and red can work well together as evidenced below.
The colour green and school in one makes me visualise Slytherin from the Harry potter films, a series of films famous for it's school of wizardry.
Hogwart's emblem makes use of 4 colours, red green yellow and blue, the red is the typically colour for Harry potter as Harry, the main character, is part of Griffindor which is represented by the reds, the green which is notoriously rather evil, is slytherin, a section which is denoted by the green shade and the snake.
Progression
From researching these colours and school's colours connotations etc, I have realised that I'd like to use the colour green in my design due to it's connection with schools and also the tone which it has such as snaky and evil, if the whole poster had this as the primary colour, it could set a tone which showed that the film was slippery, had twists and turns and wasn't an average school film. Also it is relatively a gender neutral colour which could mean it would be more applicable to a wider audience.
