Running El Capitan here. I like to turn on Reduce Transparency because I feel that the translucency in various places is distracting. However, in turning on Reduce Transparency, I am left with a dock and menu bar that is entirely too bright. I know I can turn on the "Use dark menubar and dock" setting, but that leaves the dock and menu bar entirely too dark. Is there a happy medium, perhaps a slider to scale back on the brightness of these two items while Reduce Transparency is enabled? Are there any workarounds?
