What attracted my eyes to all of these posters was their use of color. They all have very bold colors that stand out and make you want to read more into what they are going to say. In the first and second posters, the background is a plain cream color, and then the artists use bold colors with the type. The last one has a bold blue background, then a white receipt paper in the foreground but still using the same blue for the writing on the receipt. Which makes it feel cohesive. These artists also avoid common cliches, especially the poster in the middle. I think a lot of people would have used a stop sign or a hand motioning stop. This artist just made the type larger than the rest and made the font different. Then added a large, reddish organe colored exclamation point behind the type.
