Use colors that give the strongest contrast with one another. Colors with poor contrast to the background do not show up adequately. Use either light or dark background colors. It is best not to use a medium colored background, such as red or green. Good lettering colors for light backgrounds are blue, black, green, cyan, red.
Word slides Use to convey abstract ideas.
Use key words or short sentences. Use bullets and color to highlight key points. Use a series of slides to build the point when presenting longer ideas. Try to limit the content on word charts to between seven and ten lines. Select key words to focus on central ideas.
