TraditionalHumanized theme is gtk2, gtk3 theme for Ubuntu Mate 18.04. It was derived from well-polished TraditionalOk Theme. No bicycles reinvented.
The essence of TraditionalHumanized theme is that it reproduces classic Human gtk2 theme colors, uses Humanity icon set and features dimmed background colors. It does not kill eyes.
Hopefully it could help to lesser frustrations on the absence of beloved old-fashioned GTK2 Human theme in the up-to date Ubuntu Mate 18.04. At least it did for me.
