I’ve been working on some training about presentations that are accessible to people with sight and hearing challenges and have learned some techniques that I believe everyone can use.
One has to do with increasing contrast between the background (of the slide or a shape) and the text. When you do this, your colors become richer and your text is much more clear. This helps your viewers to focus on your content.
PowerPoint 365 now gives you hexadecimal stats for colors. Hexadecimal is the system used for websites. It’s similar to the RGB (red-green-blue) system that PowerPoint has used for years. I say this because the service that you can use to measure contrast uses hexadecimal notation.
