This document discusses principles of visual design including contrast, repetition, alignment, and proximity (C.R.A.P.). It provides examples of each principle and discusses their consequences when used well or poorly in design. Teachers are said to use contrast to simplify concepts for students without causing disorientation. The document also prompts discussing how contrast has played a role in the reader's life and in revelation. It includes exercises to find examples and non-examples of the C.R.A.P. principles in design work.
