Vertigo is a free Tumblr theme by Matthew Buchanan, inspired by the design work of the late Saul Bass and released 24 June 2008 under Creative Commons.
To install the theme on your Tumblr site, copy the contents of vertigo-theme-1-2.txt into the Custom HTML field of the Customize area on your Tumblr Dashboard. (If this doesn’t make sense, Richard Dunlop-Walters has a tutorial that explains the process visually.)
The theme includes a single custom colour named “Accent”, which allows you to change all the orange elements to a different shade (look in Customize under “Colors” once the theme is installed). Bright colours work best with the dark background.
