The document provides guidelines for effective design and use of style in presentations. It recommends that designs be simple with ample white space, well organized to guide the eye, and use dominant elements to divide space interestingly. To gain attention, designs should be error-free, focus on one clear idea, use headlines and large first letters, and employ framing. Color should be used sparingly as redundant cues, be easily perceptible, consistent with common usage, and avoid bleeding. Text should use a telegraphic style that follows rules of grouping items in parallel construction with font sizes of 30 points or more, and be in title case without italics. The document also provides color theory guidelines for effective use of different hues.
