Color correction volumes? Where? Behind The Scenes...VirtualProduction

Hi. Where are the “color correction volumes” mentioned in this video at 5:24?

Are these volumes proprietary or are they available to all of us? I’m familiar with post process volumes but they only work if you are in them, assuming they are not set to infinite extent, and they affect the entire screen space and not just small areas.

looks like a localized post process volume

Thanks ixicalibur for the info. Much appreciated.
