Colors available on Zorin Accent color

Under Zorin appearance, Theme, Accent color there are only six choices. Is there a utility to change this color to something other than the six available here?

Thanks, Ed

Does this answer your question How to change the folder icons color? ?

It sort of answers my question. Like Ben Morel, I was able to get closer to what I want by using Gnome Tweaks.

As best I can tell Accent Color under Theme on the Zorin appearance app sets the background color of the Super key and selections in File manager. Since I didn’t care for any of those accent colors, I sort of fixed it with changing the shell theme to Telinkrin. This fixed the Super button background, but not the file manager selections.

As a suggestion, if possible, add a few color choices that are not so bold on the background accent colors.

Thanks, Ed
