Take the website shots and blur them using PhotoShop or some other program. This should be a significant blurring like that shown in the videos. Not the simplest blurring possible from the first open source app or web page that you could find. Prepare a second PowerPoint slide for each design area that shows the blurred shots.
For each design area, use the colors from your mood design to create a simple 6 color scheme using the techniques shown in the video. Note that only the Key color and Accent colors come from your mood images. The other colors are derived from these using the 6 color scheme. Prepare a slide for each design area that shows your 6 colors and shows your test diagram using your color scheme. As you present your color scheme, not only should you show how your basic widgets should look, but also give a small sample of how the entire page might look.
In addition, pick one of the design areas and prepare an additional color scheme of your chosing. You need not confine yourself to the 6 color scheme.
Add an additional slide that describes how and why you chose the colors for your schemes.
For each design area:
For one design area a slide showing an additional color scheme
One slide of rationale for your schemes.
