Solarized is a sixteen color palette (eight monotones, eight accent colors)
designed for use with terminal and gui applications. It has several [unique
properties](#features). I designed this colorscheme with both precise
[CIELAB](http://en.wikipedia.org/wiki/Lab_color_space) lightness relationships
and a refined set of hues based on fixed color wheel relationships. It has been
tested extensively in real world use on color calibrated displays (as well as
uncalibrated/intentionally miscalibrated displays) and in a variety of lighting
conditions.

Features
--------
1. **Selective contrast**
On a sunny summer day I love to read a book outside. Not right in the sun;
that's too bright. I'll hunt for a shady spot under a tree. The shaded
paper contrasts with the crisp text nicely. If you were to actually measure
the contrast between the two, you'd find it is much lower than black text
on a white background (or white on black) on your display device of choice.
Black text on white from a computer display is akin to reading a book in
direct sunlight and tires the eye.
![solarized selective contrast](https://github.com/altercation/solarized/raw/master/img/solarized-selcon.png)\
Solarized reduces *brightness contrast* but, unlike many low contrast
colorschemes, retains *contrasting hues* (based on colorwheel relations)
for syntax highlighting readability.
2. **Both sides of the force**
![solarized dualmode](https://github.com/altercation/solarized/raw/master/img/solarized-dualmode.png)\
I often switch between dark and light modes when editing text and code.
Solarized retains the same selective contrast relationships and overall
feel when switching between the light and dark background modes. A *lot* of
thought, planning and testing has gone into making both modes feel like
part of a unified colorscheme.
3. **16/5 palette modes**
![solarized palettes](https://github.com/altercation/solarized/raw/master/img/solarized-165.png)\
Solarized works as a sixteen color palette for compatibility with common
terminal based applications / emulators. In addition, it has been carefull
designed to scale down to a variety of five color palettes (four base
monotones plus one accent color) for use in design work such as web design.
In every case it retains a strong personality but doesn't overwhelm.
5. **Precision, symmetry**
![solarized symmetry](https://github.com/altercation/solarized/raw/master/img/solarized-sym.png)\
The monotones have symmetric CIELAB lightness differences, so switching
from dark to light mode retains the same perceived contrast in brightness
between each value. Each mode is equally readable. The accent colors are
based off specific colorwheel relations and subsequently translated to
CIELAB to ensure perceptual uniformity in terms of lightness. The hues
themselves, as with the monotone \*a\*b values, have been adjusted within
a small range to achieve the most pleasing combination of colors.
This makes colorscheme inversion trivial. Here, for instance, is a sass
(scss) snippet that inverts solarized based on the class of the html tag
(e.g. `<html class="dark red">` to give a dark background with red accent):
$base03: #002b36;
$base02: #073642;

Installation
------------
Installation instructions for each version of the colorscheme are included in
the subdirectory README files. Note that for Vim (and possibly for Mutt) you
may want to clone the specific repository (for instance if you are using
Pathogen). See the links at the top of this file.
Font Samples
------------
Solarized has been designed to handle fonts of various weights and retain
readability, from the classic Terminus to the beefy Menlo.
