# Viewing a Key with a Solid Colour Background

While creating the key, you can view the composite using a solid colour for the background in place of the back clip. This can help you see details in the image, such as colour spill, that you may otherwise miss. You can use the default colour (black) or select a colour using the colour picker.

NoteThis view does not affect the final render.

To use a solid colour background:

1. In the View box, select Comp.

   A colour pot appears.

2. Click the colour pot above the Comp view output option.

   The colour picker appears.

3. Select a colour for the background using the colour picker.
