I'm not sure where to find the corresponding change in R. Can you point to an R NEWS entry or (even better) a svn revision?

Not sure what you mean, but hopefully this can point you into a direction, from the official dev blog of r-project.org:

hcl.colors(): https://developer.r-project.org/Blog/public/2019/04/01/hcl-based-color-palettes-in-grdevices/

palette.colors(): https://developer.r-project.org/Blog/public/2019/11/21/a-new-palette-for-r/
