You are particularly interested to know which color givespeople a sense of serenity and peacefulness. You conduct an experiment bymaking participants stay for 20 minutes inside a room painted with a particularcolor (e.g., Red, Orange, Yellow, Green, Blue). With the use oftemperature-sensitive cameras, you record the average body temperature of eachindividual during their stay inside each room (i.e., lower body temperatures areassociated with feelings of calmness and relaxation; higher body temperatures -stimulation, excitement).
