Just keep in mind, that you dont want to change $c variable to hardcoded value here - sometimes button can have different colors (suggestive, destructive, infobars etc), so you need to set color relative to $c. - Apr 17 2019

I guess you talking about active tab background - it looks like it interferes with window content. Actually, it’s not, and both active tabs looks the same way, you can see it on this screenshot with zoomed widgets https://ibb.co/mhYsP2H Second screenshot shows how those widgets looks like in native gtk2 application - window content below tab has border https://ibb.co/qBHrD0r So, the problem here is not with the theme, but with qt5gtk2 engine, probably, it uses widgets wrong way (and this tab bar is a bit hacky, but all the related code was forked from Adwaita gtk2 theme - default one - and I prefer keep changes to minimum). I cant help you here. You can try to add border for window content that is below the tab bar (not sure if it is possible). Also, afaik, qt5gtk2 engine is unsupported and was dropped from qt5. I use qt5 applications with Fusion theme (with some color adjustments) - it looks different, but works without issues.

You can open src/gtk3/_colors.scss and edit accent color variables. First pair is $selected_bl_color and $selected_fl_color - colors used for (not-only) text selection (light background/dark foreground), the second pair is $selected_bg_color and $selected_fg_color - darker accent color with light (matching) foreground color. Then, you should change accent color (selected_bg_color) for gtk2 theme in src/gtk2/gtkrc (and, probably, matching selected_fg_color too). For best experience, you should also modify colors on gtk2 assets (like progressbar, selected entry border, etc) - edit src/gtk2/assets.svg - replace colored elements with color you want in inkscape and re-render assets with render-assets.sh script in the same directory (by default it will override existing assets files).
When you made changes, continue with regular installation procedure. - Dec 16 2018

Looks like meson version is too old in debian stable. Required version is 0.40+. You can try download already built theme from Fedora copr repo https://copr-be.cloud.fedoraproject.org/results/monday15/lounge/fedora-28-x86_64/00830455-lounge-gtk-theme/lounge-gtk-theme-1.7-1.fc28.noarch.rpm (it is an archive file, just extract it somewhere, then copy Lounge folder to ~/.themes). Not sure how it will look though.

Yep. It supposed to be at right side, but afaik propor positioning only possible with creating extension for gnome-shell (margins in percent doesnt work). So, right now swither is at far right side on 1280px width screens, but on 1920 it is a bit closer to center. I dont like centered switcher, because it steals focus (I use workspaces a lot), with swither on the side it easier to imminently catch what's opened on current workspace.
