This study mainly focuses on mini-dolls hairstyle, or more specifically the hair colour, to explore whether the composition of the mini-dolls hair colour reflects the pursuit of diversity. As the LEGO mini-doll audience is mainly youth, it needs to be compared with real-life to explore whether the mini-doll constructs a world close to the real one and contributes to the construction of youth worldview. Secondly, it may be evident that LEGO started to experiment with new explorations in 2012 to tap into the female market. Therefore, the number of Sets produced by LEGO since 2012 will also be visualised and used to explore the construction of the LEGO world.
