Did you know that seeing the colors red, orange, and yellow make you feel hungry?

Now you know why fast food restaurants always use these colors! In fact, every single color we see can impact a multitude of things from our appetites, to our emotions, and even our personal beliefs. Depending on how you use these colors, (especially in advertising) you can get a general feel of things. For example, an advertisement using the color blue can generate a feeling of trust and calm, while an advertisement that uses red can be seen as bold, attention grabbing, or urgent.
