Color Palette Question

I’ve been trying to figure out why my color palette in sketchup make (mac os 10.13.16) looks like this (hue jumbled) rather than what I’m accustomed to which is colors of the same hue grouped together and ordered by increasing intensity, like the second embedded image. materials_window|233x347


It’s a Mac thing. There have been other threads on this topic.


Thanks for an excellent explanation.
