There exists a large body of anecdotal knowledge linking particular colours to specific psychological moods, red being described as an “active” or “aggressive” colour and on the other hand blue as being calming, for example. This mood-altering influence has been investigated in studies from various fields. These studies use short to medium times of color exposure. Evidence from EEG studies, for example, suggests that short exposure to red colour elicits an anxiety state which causes increased brain activity. However, to our knowledge there are no studies concerned with the effect of long-term (more than an hour) exposure to a colour, in particular when colour vision is completely altered, on psychological mood and brain activity. Our study will address this research gap.
