No this blog is not about literal crap, but it is the acronym for Contrast, repetition, Alignment, and Proximity. This lovely, humorous acronym was created by Robin Williams (not the actor). He is the author of The Non-Designer’s Design Book. I think contrast is the most important design concept within the acronym. Contrast is making elements stand out without making them slightly different. Different contrasts allows the viewer to connect the flow easier. Contrast is also visually appealing, because it makes important information stand out. This design concept makes things more visually interesting and communicative; which are two elements that are important when attracting an audience. The most important thing about designing is that you want your audience to be interested in what you have to say and contrast can attract that audience.
