Place most important text at the top and in the brightest color. Use text justification commands to align text rather than using the tab keys or space bar as these may make text appear to be aligned on your computer screen but will not be on your output. Use build or reveal series to introduce your information, one line at a time. Color Color must be seen when superimposed on a background of another color. Foreground and background elements must have enough contrast between them.
Inappropriate colors can interfere with legibility.
Too many colors can distract from your message. For slides and computer screen shows, use dark blues, darker grays, dark greens, and black for the backgrounds. Use yellows, light reds, and white for the text and graphics. Medium blues, purples, greens, and magentas or maroons work well for background colors, especially gradient backgrounds fading to an almost black color. Use color to differentiate, group, emphasize, prioritize, and identify recurring themes.
