Color Play

When creating presentations, one must keep in mind of color use because they do invoke certain emotions or attract attention in audience members. For instance, cool colors (e.g., blue, green) tend to recede and thus make excellent backgrounds. On the other hand, warm colors (e.g., red, orange) highlight visuals because they advance toward the audience. Thus, one would want to reserve these colors only for emphasis or stimulating audience's emotions.

Color psychology says that:

Green signifies growth and emotion.
Blue is universally liked. It conveys calmness,
but looks institutional and fades faster than any other color.
Blue elements receive less of audience's attention.
Red can stand for power, energy or danger,
but can be difficult to see at a distance.
People tend to recall information in red longer.
Yellow is usually thought of as a positive color.
It works well for highlighting against a dark background.
People tend to look at yellow objects first.
However, most people tend not to like yellow,
and thus, should not be used as a background.

However, when deciding upon a color, one also has to take cultural differences into account . For instance, red for Americans tend to stand for power, energy, or danger. However, in China, red stands for luck and prosperity. White for Americans convey nutrality and serenity. Nonetheless, white represents death to the Japanese. So, just be cautious when selecting colors, and keep in mind that each presentation should not have more than three different colors.
