Use the colour pots in the Modular Keyer menu to compare colours from two different images, or from the same image as it appears in different parts of the pipeline. To do this, you pick the colours from each image and apply them to the two colour pots.

You can also apply a colour that you copied to a colour pot to a colour pot in one of the node menus. For example, apply the colour to the Suppress Colour pot in the Colour Curves menu.

To apply a colour to a colour pot:

1. Display the image with the colour you want to sample.
2. Click the colour pot.

   The colour picker appears.

3. Click Pick and then click in the image on the colour.
4. Click in the colour pot again.

To copy a colour to a colour pot in another menu:

1. Open the node menu containing the colour pot you want to copy a colour to.
2. Click in the colour pot in the node menu.

   The colour picker appears.

3. Click Pick, then click in the Modular Keyer colour pot containing the sampled colour.
4. Click in the node menu colour pot again.
