Simple lxde-meta
It worked fine for me with adequate contrast for many weeks. However I eventually found that when I would look away from the screen and across the room that the entire room was grayscale with no color for a second or two.
I took the hint that the colors I had chosen probably weren't good for my eyes and changed the color scheme.
Some time ago I tried some of these KDE extras installed via sysutils/plasma5-discover. They were all missing something, like icons or such. Now I use the traditional Air+Oxygen theme with a random picture of the day background image from Unsplash Wallpapers & from Wikimedia Commons for the screensaver.KDE Theme: https://github.com/vinceliuice/McMojave-kde

An empirical explanation of color contrast
For reasons not well understood, the color of a surface can appear quite different when placed in different chromatic surrounds. Here we explore the possibility that these color contrast effects are generated according to what the same or similar stimuli have turned out to signify in the past...www.pnas.org

I wonder if there is a theme fixing those Gnome 3 style inconsistencies. (Rounded corners at the top of the dialog window vs non-rounded corners at the bottom, off-center button labels and spacing in general.)Xfce 4.16
Unlikely. Mainly because theme authors know that any time and effort spent fixing this kind of stuff will be broken next release. The development style of GNOME-like desktops these days means that polish is not possible.I wonder if there is a theme fixing those Gnome 3 style inconsistencies.
