# Colour Correct Node

Use this node to apply colour corrections to the front, back, or key-in clip using the Colour Corrector.

You can add Colour Correct nodes to any part of the pipeline except to the Front and Matte pipes of MBlend nodes and the Matte pipes of CBlend nodes. This is because these pipes are designed to produce a matte, and the result of the Colour Correct node is a colour image.

When using the Colour Corrector from the Modular Keyer, select a view from the Reference box and View box, while subsequently using the reference clip to compare your result. See Storing Reference Frames in the Reference Buffer.

The View box includes views for Context Point 1 and Context Point 2 while colour correcting the clip. See Setting a Context Point.

To use the Colour Correct node:

1. Add a Colour Correct node to the pipeline:
   - If you are colour correcting an entire image, attach a single input to the Front tab.
   - If you are colour correcting a portion of the image, attach the front image to the Front tab and the matte to the Matte tab.
   - If you are colour correcting a composite, attach the front, matte, and back images to the Front, Matte, and Back tabs. This allows you to colour correct the front image only (while viewing the whole composite).
   NoteWhen you add the Colour Correct node to the Front pipe of the CBlend node, the region to which the colour correction is applied is defined by the Matte pipe. See Using Blend Nodes for more information.
2. Click the Colour Correct node.

   The Colour Corrector menu appears in the menu area.
