Yep, I posted this link downstream a little bit ago. The processes different people use are interesting.
What's fun is that we are so tuned to color differences that a slight change in the algorithm — what color it "resorts to" if the desired one is used — might produce a small absolute difference (distance-wise on the table) but a massive perceptual difference, or create a much greater effect far down the line when greens were exhausted early or unused bright reds are speckling a neutral zone. Certainly an interesting exercise!
