We felt that the pavilion needed some sort of coloured element to bring into a more 'disaster' realm rather than a 'depression' one. We set the boards next to some colours to see what they looked like together.
The orange worked best as it refers to the main colour of spray paint used after the earthquake and also has a 'danger' element to it. The orange also really pops and brings attention to the phone which is the focus of the pavilion.
