Ferdinand De Saussre was the creator of the Semiotic Theory, he believed that we interpret the signs that we recieve based on our feelings, moods and emotions. For example the colour Red may be used to promote anger or violence, or pale blue to promote calm and peaceful emotions.
The proccess was designed as: Sign>Signifier>Signified
Or in other terms: Sunshine>Peaceful music>Happy
This can be used in nearly all aspects of media, including magazines, which is where I will use it. I can relate colours to specific topics in the text, and I can use themed shades and pictures to illustrate and enhance the fact that my magazine is aimed at people who enjoy heavy metal music. Typically I will use darker colours for backgrounds with lighter more contrasting foreground to lift the page and make it more appealing for viewers.
The colour scheme may change from each issue the magazine releases.
