How can I recolor the PNGs in the Design Elements Category?
It depends on which version of PowerPoint you are using. We're using the de015 corners as an example for this FAQ.
- Pre-PowerPoint 2007: even though the corners are
PNGs and are not eligible to accept line and fill colors, over-/underlaying
fields that have colors, gradients, and some transparency add a nice effect (see example below).
The series example uses a gradient overlay like this.
- PowerPoint 2007: You can use the same technique as above in PowerPoint 2007, or you can apply color presets to the corners as shown below.
