Color psychology is an interesting field, and one that you can draw on to make a successful PowerPoint presentation. You want to use meaningful and memorable colors, but you don't want to get too busy or flashy. PowerPoint is an extremely versatile program, but that doesn't mean you need to exploit every gimmick and design trick available.
Rather, look for ways color combinations can assist you in delivering both the contextual detail and the emotional impact in each slide you craft, so they support your message succinctly, clearly and intuitively. A vivid contrast or a soothing balance might be called for to help make your points. By using complementary colors (those opposite on the color wheel) and analogous colors (those adjacent on the color wheel) you can affect how your audience perceives your message. Also, let colors work for you. Green is commonly associated with both action (such as at a stoplight) and wealth (the old greenback) so you might want to employ it strategically if you're hoping to convey these sentiments.
