Easy-to-read Color Scheme
Even though there is a whole rainbow of colors to choose from in a lot of presentation programs, you shouldn’t use all of them. Instead, stick to a color scheme. A color scheme is a combination of matching colors that are used throughout the presentation–you want to make sure the colors are easy to read on the screen.
Really bright colors on a white background can be hard to read for many people. If there’s a glare on the screen from the Sun or a light bulb, it’s nearly impossible!
This doesn’t mean you have to stick with black text and a white background throughout your presentation. In fact, using a handful of different colors draws attention to important points. Don’t use more than two or three text colors in your presentation–reading a whole rainbow of words is distracting.
Bright colors read well on a black background.
Dark colors read well on a light background.
