Abstract: An integrated psychophysiological study was made for investigating the impact of |red colour| on bodily reaction induced by stress. With regard to the psychophysiological measures, we assayed salivary-secreted substances such as hormones and immune substance as introductory novel biometric. We compared with conventional physiological measures such as Heart Rate (HR), blood pressure and Skin Temperature (ST). As a result, some biomarkers depicted a marked difference between the red and the control conditions: in the red condition, observations showed a steeper elevation during the stressful task and a sparse recovery during the rest. The results suggest the possibility of the substance-based evaluation of the effect of colour on human physiological state.

Keywords: psychophysiological research; red colour; stress; biomarker; saliva; bodily reaction; biometrics; hormones; immune substance; heart rate; blood pressure; skin temperature; stressful tasks; physiology; psychology.
