Changing the Background Color
The default background in After Effects is black, which makes it hard to see holes or other errors when pulling a key. So you'll start by changing the background to something other than black or white. In this exercise, you'll use orange.
- Choose Composition > Background Color or press Ctrl-Shift-B (Mac OS: Command-Shift-B).
- Click the color swatch and select a bright orange hue, such as RGB 255, 200, 0 (see Figure 3). Then click OK to close the Color Picker, and OK again to close the Background Color dialog box.
