7. Be Visual
- The impact of visuals is greatly increased by colour IF it is used well.
 - Ensure there is a clear contrast between text and background colour.
 - Use a highlight colour to emphasis key words.
 - Don’t use too many colours on one slide.
 - Use colours that harmonise rather than clash. Bright shades can look harsh when projected.
 - If you’re not sure how to put colours together, make use of the colour schemes available in PowerPoint.
