Overview Outline key points in talk to provide structure and help audience organize information. Presentation Use as many slides as appropriate.

Warm colors, such as yellow, orange, and red, provide pleasant if not dynamic reactions. Cool colors, such as green or blue, evoke a quiet mood and are less outgoing than warm colors.
