 The first psychological hack is the psychology of color. Friends, believe it or not, colors has a huge impact to the way we think and the way that we behave. In addition to that, we also associate certain memories, certain emotions, and certain characteristics to color. Just like how when we see the color red, what is the first thing that comes to mind? Aggressive, passionate emotions. Whereas pink is feminine, it is playful. Now, since colors play such a big role in your emotions, characteristics, and your behavior, you bet that these big brands pay close attention to the colors that they use.
