16 guests equipped with brain wave headsets experienced 8 environments in 8 different colours. Each setting was designed with restaurant attributes completely covered in a monochrome colour – from walls and floor to furniture and tableware.
For each colour experience the guests were asked to taste a drink and a miniature Macaroon cookie – identical in all aspects except for the colour, matched to the surrounding environment. For every setting, brain activity and heart rate was measured, alongside a questionnaire to inventory the reactions from the participants. All data from the testing has been analysed to create a profile for each colour.
