Color is considered one of the most useful and powerful design tools you have. It is far more complicated and involved then you may realize, that is why we have begun understanding design principles in this class using only black, white, and gray tones.
People respond to different colors in different ways, and these responses take place on a subconscious, emotional level. Understanding how color works, what certain colors mean, how should it be used in graphic design are all "in-depth" studies that couldn't possibly be explored properly in just one sitting... or just one class for that matter. My hope is that this is a beginning point of your education with understanding color theory.
The following link is an interactive web site to help us get started exploring color on a basic level...
