They claim that the new scale gives a continuum from dark to light, but if you look at the example it goes dark at both ends with the brightest colors in the exact middle. Why the discrepancy?

I don't think it does. The picture here: https://static.scientificamerican.com/sciam/assets/Image/UPj... is CVD-Jet, not their new scale. The blue-and-yellow rightmost picture is described as "as a person with red-green color blindness sees the rainbow image [in the center]". This scale does put the brightest colors in the center.

Their proposed scale, cividis, does not have a brightness in the middle of the scale. It's the second image in the article: https://static.scientificamerican.com/sciam/assets/Image/jou...

Correct, one of the links in the article shows a pretty clear comparison between rainbow scale, how that looks to someone with color deficiency (with the dark portions on the ends), and their proposed scale.

Thanks. They sure made it confusing with their choice of examples then.
