Out of curiosity, what are the advantages of the HCL colormap over YlGnBu
for continuous values? I'm biased towards YlGnBu because green is my
favorite color and want to know what makes HCL objectively better for
perceiving values.
I added YlGnBu_r versions of those plots just below yours:

It seems it's a little more "extreme" than HCL, as in it lights are lighter
and its darks are darker. From the color research, is this less desirable?
