Use Colour Source to generate a colour bar, noise, gradient, or colour clip that can be used as the clip for other nodes.
To access the Colour Source menu, use:
Timeline, then use ConnectFX (see Creating ConnectFX).
Tools, then select from the menu (See Accessing Tools).
The Modular Keyer, then select a node from the Node bin.
This node outputs a result.
The Colour Source node includes eight colour pots for storing and selecting customized colours for creating frames. You can specify a frame's resolution and bit depth.
