In 2015, we launched the data collection on our international colour-emotion association survey. The data is collected online (https://www2.unil.ch/onlinepsylab/colour/main.php). We invite participants to complete the survey in their native language. At the end of 2017, we had translated and back-translated the survey into 37 languages. Additional translations are ongoing or are waiting for opportunities (new collaborators). For each country or language group within a country, we aim for complete data from about 100 participants, roughly equally distributed between three age ranges (18-30 years; 31-50 years; > 50 years). Also, we do not treat the data set without having at least 25 valid responses in each age group. Thus, we treat each sample when these conditions are met. On the current webpage, we only publish data of completed countries. We here use country of origin (not country of residence) as variable to group participants into discrete clusters per country. Different groupings can be obtained from the complete dataset.
