Example

# zathurarc config sample ... # colors set default-bg "{{background}}" # complementary foreground, but keep it light set default-fg "{{foreground | complementary | lighten(0.5)}}" # make it a bit lighter than background set statusbar-bg "{{background | lighten(0.3)}}" # make it darken by blending to a darken color set statusbar-fg "{{foreground | blend("#eeeeee")}}" # use it's complementary set inputbar-bg "{{background | complementary}}"

Then you can add this file to ~/.config/wallust/templates and use the config file to template it. For example, zathura.template = 'zathurarc', and then define a target field, see config.
