A rofi theme based on the Solarized color scheme but a bit darker. I love solarized but I want some contrast in my launcher. Here's a screenshot:
Note that I'm showing 15 lines and using System San Francisco Display 18 as my font (see installation notes for additional info).
Assuming you have the latest version of rofi properly installed, you can install/update this theme using the following command:
sudo curl -o /usr/share/rofi/themes/solarized-darker.rasi https://raw.githubusercontent.com/DeanPDX/rofi-solarized-darker-theme/master/solarized-darker.rasi
Next you need to select the theme. I use i3wm so I just bind the following to my launcher keystroke:
bindsym $mod+d exec rofi -show run -lines 15 -font "System San Francisco Display 18" -theme "solarized-darker"
As you can see, I am passing the theme in as an argument. You can also launch rofi-theme-selector and preview/select the theme that way.
The theme is also available in the User Themes section of the official rofi-themes repository.
