Creative International has a wide variety of Abstract Powerpoint Backgrounds that are boldly infused with a variety of color. When using these backgrounds the most important rule is to make sure that your background and foreground colors are well contrasted to make your text more visible. For best results always use light text over a dark background and dark text over a light background. Avoid having similar text and background colors. It is always a good idea to check your presentations in grayscale. If colors are well contrasted in grayscale they will work well in color. To view your Powerpoint presentation in grayscale start the grayscale preview by choosing View- Color/Grayscale-Grayscale. To get back to the normal color view choose View-Color/Grayscale- Color.
TIP
Don't copy and paste pictures and other content from the internet into PowerPoint
Instead, right-click the picture, choose Save Picture As and save it to your hard drive. Then use Insert, Picture, From File to bring the picture into PowerPoint.
If you copy paste from the net, you run the risk of creating a hard-to-remove link to the internet from your presentation. This may cause Windows to try to connect to the internet every time anyone opens the presentation. A real annoyance if ever there was one. And one that can be darned hard to track down and get rid of.
Don't link images
When you use Insert, Picture, From File to insert a picture into PowerPoint, you may notice an option to Link to the file. Unless you have a good reason for doing it, don't. PowerPoint's image links break very easily. It's generally safer and more effective to embed the files (in other words, insert them normally, not linked).
