Use Colour Curves to access a clip's colour menu, remove colour spill from a front clip, and perform a hue shift.
To access the Colour Curves menu, use:
Batch, then select a node from the Node bin.
Timeline, then use Batch FX (see Creating Batch FX).
The Modular Keyer, then select a node from the Node bin.
This node accepts a front clip, and outputs a result.
