Making highlight color darker
A previous response to this question suggested using Accessibility in System Settings to increase contrast and/or reduce transparency. But when I open Accessibility, those utilities—Increase contrast and Reduce transparency—don't respond to my clicks. Neither does Display contrast. In fact, none of the options, whether under Display or Pointer, responds to clicks. The highlight color is way to faint for me to see, most of the time. Any ideas on how I can make it darker? Any and all suggestions gratefully received.
