Labburn is a port of the Zenburn for Emacs theme, which in turn is is a direct port of the popular Zenburn theme for vim, developed by Jani Nurminen.
The main change is the movement of color defintions to the Lab Color Space, which allows better manipulation and comparative equality in perception of the lightness of different colors. Colors were converted from the zenburn theme and slightly adjusted in lightness.
All/most bold attributes were removed as well, as these change the lightness perception. Development of the original zenburn theme is tracked as far as appropiate, last merged commit was 6ca85d248468639650fcce2c2d13c46c6e99ded3. The theme is made to be used with the rainbow-identifiers package, please enable this. License GPL 3
