This is a theme using Ethan Schnoover's Solarized color scheme, with the proper background and foreground sets. Additionally, it defaults to Menlo, as we programmers like our monospaced fonts (easier to read). It uses yellow for the selected result highlight, with blue and magenta button accents. The fonts are on the big side, with the window being made a bit wider. Hope you like it!

Alfred Themes are imported via a URI scheme. So, when you click on the + Import Theme link, the Alfred2 Preferences window will open, asking you if you want to import the theme. There are no files to download, and, also, because of that, themes cannot be auto-updated.
