Is there an easy way to generate a list of CMYK color values that will appear identical to the human eye under 589nm light?

Here’s the Wikipedia section one general colour space, with a pretty diagram of chromaticity, and the one on CMYK colour conversion. What you want is the preimage of a CMYK colour projected into the entire perceptual space.

CMYK actually sounds kind of complicated to do this with, so yeah look for a pre-made function to convert CMYK to CIE 1931 in whatever “normal” light you have. I can help you find the preimage from that once you do.

Edit: Oh wait, this was a Halloween thing. Maybe for next year?
