Notes:
Also sometimes called greenscreen or chroma key technique.

The foreground action (such as a weather reporter) stands in front of a single-color background. Any color can be used, but generally blue or green are used because they do not conflict with skin tone. A computer then replaces the background with other footage or effects.

The best color to use depends on various circumstances. Click on the Wikipedia link for more detail.
