A novel 'qualia structure' paradigm uses relational similarity judgments among color qualia instead of verbal reports to study the neural basis of consciousness. An fMRI dataset was collected from 35 participants who made relational similarity judgments between two of nine color qualia per trial. Half of the trials included a 'no-report' condition to assess the effect of overt reporting. Each participant's color discriminability was also measured with a hue test outside the scanner. The data provide insights into brain functions associated with color qualia and the neural foundations of consciousness.
