Why graphic design they ask? Graphic design to me is a way of communication that helps the public understand what that specific company wants to portray or relay to their clients in the future. It can start with a color choice, composition, or text and if that one specific quality is the wrong choice that company may suffer. Although, the good things that can come out of good design are so great, because it impacts so many people without them even realizing it.
Design is in everything around us. You're designing right now, from your clothes to how you eat your food. It's impossible to not use design, I just would like to see how far I can take it.
