Aggression

You are more likely to change your views and agree with people wearing black. It is not clear exactly how colour influences our perceptions but researchers argue black is often perceived as more aggressive than other colours. This perceived aggression may make us more susceptible to conforming to the views of the person.​

In one study, for example, participants were more likely to deliver a guilty verdict of an innocent person if they were working with others wearing black and who were intentionally trying to sway the verdict to guilty. The same influence was not present when those people wore white.
