Abstract
This study aims to add to previous research on red, blue and white coloured lighting and the effects it may have on diastolic and systolic blood pressure, heart rate, mood and stress. Coloured light bulbs were used to create the desired environment, with effects counterbalanced to avoid order of effect. Each condition was administered in five minute segments. This was a within subjects, quasi-experimental design. Thirty participants (n=30) were examined in total during this experiment. Brief Mood Introspection Scale by Mayer and Gascher (1988), was used to gain mood scores and Smith Relaxation States Inventory, Smith (2005) was uses to obtain stress levels in participants. The results indicated no significant differences for blood pressure, heart rate, mood and stress under red, blue and white coloured lighting.
