Comparison Among Three Methods for Thai Colour Naming

We conducted experiments in colour naming and colour categorisation in Thai to facilitate colour communication within and across cultures. In this study, we compare the frequency and location of Thai basic colours terms (n=11+1) in three experimental methodologies - two conducted in controlled viewing conditions (classical and category) and one over the Internet. Although the frequencies of colour names across the methods were different, they produced ranks within each method that were only slightly different compared with the ranks obtained in the other 2 methods. In terms of hue and lightness the agreement was relatively good for most colour terms but we found large differences in chroma
