Color can emphasize key areas, but do not over use colors or they will become distracting. Avoid colors far apart in the spectrum, e.g., red and blue, together. If your illustrations include tables of data, avoid presenting too much information in a single table. The data will run together and your audience will lose interest rather than try to hunt for the key information. Highlight the key data and include only a few other examples.
Presentation Speak loudly and clearly.
If you are using a microphone, find the proper position for your head and try to stay as close as possible. If you use a projection pointer, rest your elbow on the podium or table or press your forearm to your side. This will help keep the pointer steady. If using an overhead projector, lay a pencil directly on the transparency to point out information. A constantly jiggling pointer distracts your audience and makes them think you are nervous and uncertain of your topic.
