Color psychology plays a huge role in how your buy items. It can change your mood, evoke a feeling, and even subtly suggest an idea. For example, red is a frequent color in sales since it evokes action, which definitely helps explain all those impulse purchases at Target. A study even found that waitresses who wear red get bigger tips. Other colors that manipulate you is black, which is associated with high-end, expensive items that seem exclusive, and blue, which is associated with trust and loyalty.
