The association tests that synesthete.org run don't use a grapheme -> categorized color task, but instead ask the user to visually select a color on a color map

The association tests that synesthete.org run don't use a grapheme -> categorized color task, but instead ask the user to visually select a color on a color map. This way, not only the reaction time, but the variance of selection can be observed. Also a bit surprised that the article mentioned nothing about Eagleman's research on this stuff.
