The rihanna concert poster is very simple, although it follows typical conventions of an R'n'B music poster, due to the element of sophistication through the use of a strict colour sceheme of red, white and black which creates a classy image.
The use of red is only used a her hair colour; this attracts the audiences eye striaght away and is the main focal point when you look at the poster.
The name of the artist 'Rihanna' is written just below her face with a big font and is written in white which connotes purity and femininity. The artists name is important as the audience need to be able to identify the artist.
Rihannas face takes up the most of the poster which shows the significance of the artist and shows the audience who will be the main focus during the tour.
The name of the tour is the same as her album which is important for it to be the same and on the poster as the audience will need to know what songs she may sing.
Coming towards the end of the poster the poster becomes more darker and then the information that is required is written in white and lilac which stands out. These are codes and conventions of a tour poster.
