Despill and chroma keying blinkscript-based gizmo, with image-based input options and capable of despilling any hue you pick (and not only the primaries), selecting different algorithms for de/respilling, and protecting desired tones.

apDespill v2.0 is a blinkscript despiller and chroma keyer capable of picking a specific tone and with image-based input options for most of the controls. v2.0 lets you choose between a despilling and keying algorithm, bringing new options such as turning the despill into a color or using it as an iKeylight. |
If you just want a basic despill, its default values should already be enough and the tool will avoid any extra calculations.
v2.0 includes a new 'absolute' mode which lets you basically perform a key, or do a 'despill to color' operation. Also, the despill color, respill color and limit can now be plugged as image inputs if you wish, letting you perform a fully image-based despill or key, sort of iKeylight. Additionally, it allows you to perform the despill under a colorspace sandwich, for the artists who prefer to loop through different colorspaces in order to find one that works. Thanks to Tony Lyons the best feedback!
Image-based inputs
Image-based inputs let you use a single apDespill node for performing a different operation for every pixel of the image.
Absolute mode
With the new absolute mode you can change the despill algorithm (which removes the excess of a primary colour) for a chroma keying algorithm (which removes all of the presence of a specific tone), allowing for a despill-to-color operation or even using the tool for chroma keying (image based!).
Specific tone despilling
Since v1.0, the main distinct feature of apDespill is the possibility to despill a specific tone picked from the image, not being limited to pure red green or blue. This is internally performed via hue rotations.
apDespill is also part of Nuke Survival Toolkit: https://github.com/CreativeLyons/NukeSurvivalToolkit_publicRelease
