Each swatch should be a solid color and a different specific
position in the RGB curves graph. I don't have Nuke in front of me, but
you should be able to sample each swatch on the source and destination
images and create several keys in the curve graph.

Subject: Re: [Nuke-users] match color charts between HDR and plate for every
color swa
I haven't tried the ColorLookup node for this. But say I matched the first
swatch, how can I match the next swatch with the ColorLookup without affecting
the first swatch that I just matched (and moving forward to match all remaining
swatches)? This is the part puzzling me....
