# RNB, A VIM COLORSCHEME TEMPLATE
# Author: Romain Lafourcade (https://github.com/romainl)
# Canonical URL: https://gist.github.com/romainl/5cd2f4ec222805f49eca
# This template is designed to help vimmers create their own colorschemes
# without much effort.
#
# You will need Ruby to generate your colorscheme but Ruby knowledge is
# not needed at all.
#
# The process is divided in four steps:
# 1. start by editing your colorscheme's information,
# 2. define your colors,
# 3. define your highlight groups and links,
# 4. and generate your colorscheme.
# Step 1: information
#
# Make sure the name of your colorscheme is unique and attractive.
# The description should fit in a single line with no linefeed.
# 'background' can be "light" or "dark".
information = {
author: "foo",
email: "foo@foo.foo",
name: "bar",
description: "Lorem ipsum dolor sit amet.",
background: "light",
webpage: "http://www.example.com"
}
# Step 2: colors
#
# black = [ give each color a distinctive name
# "#000000", hexadecimal color for GVim/MacVim and "true colors" terminals
# 0, integer between 0 and 255 for terminals supporting 256 colors
# "black" color name for less capable color terminals, can be "darkred", "red",
# "darkgreen", "green", "darkyellow", "yellow", "darkblue", "blue",
# "darkmagenta", "magenta", "black", "darkgrey", "grey", "white"
# ]
#
# If your colors are defined correctly, the resulting colorscheme is guaranteed
# to work in GVim (Windows/Linux), MacVim, and any properly set up terminal emulator.
#
# The colors below are the first 16 colors of the xterm palette. They
# are only here as an example so you can get rid of them, I won't be mad.
black = ["#000000", 0, "black"]
darkred = ["#800000", 1, "darkred"]
darkgreen = ["#008000", 2, "darkgreen"]
darkyellow = ["#808000", 3, "darkyellow"]
darkblue = ["#000080", 4, "darkblue"]
darkmagenta = ["#800080", 5, "darkmagenta"]
darkcyan = ["#008080", 6, "darkcyan"]
gray = ["#c0c0c0", 7, "gray"]
darkgray = ["#808080", 8, "darkgray"]
red = ["#ff0000", 9, "red"]
green = ["#00ff00", 10, "green"]
yellow = ["#ffff00", 11, "yellow"]
blue = ["#0000ff", 12, "blue"]
magenta = ["#ff00ff", 13, "magenta"]
cyan = ["#00ffff", 14, "cyan"]
white = ["#ffffff", 15, "white"]
# Step 3: highlights
#
# You can define highlight groups like this:
#
# [ "Normal", name of the highlight group
# white, the color used for background color, or use "NONE", "fg" or "bg"
# darkgray, the color used for foreground color, or use "NONE", "fg" or "bg"
# "NONE" style, can be "bold", "underline", "reverse", "italic",
# "standout", "NONE" or "undercurl"
# ]
#
# The sample above tells Vim to render normal text in dark gray against a white
# background, without any styling.
#
# or link an highlight group to another:
#
# [ "Title", "Normal" ]
#
# In GUI Vim, there is an additional color for the undercurl used to
# highlight spelling mistakes:
#
# [ "SpellBad", name of the highlight group
# "NONE", the color used for background color, or use "NONE", "fg" or "bg"
# red, the color used for foreground color, or use "NONE", "fg" or "bg"
# "undercurl", style
# red color used for the undercurl
# ]
#
# The sample above tells Vim to render badly spelled words in red against the current
# background, with a red undercurl.
#
# You can add any custom highlight group to the standard list below but you shouldn't
# remove any if you want a working colorscheme.

[ "Normal", white, darkgray, "NONE" ],

# From a separate shell:

# $ erb -T - bar.erb > bar.vim

# From Vim:

# "I Made My Own Colour Scheme and You Can Too!"
# A few general advices:
#
# * The Windows console is limited to the 16 so-called "ANSI" colors but it has
# a few of them interverted which makes numbers impractical. Use color names
# instead of numbers: :help cterm-colors
# * The Windows console (yeah…) doesn't do italics, underlines or bolded text;
# it is limited to normal and reverse. Keep that in mind if you want
# your colorscheme to be usable in as many environments as possible by as many
# people as possible.
# * All of the terminal emulators in use these days allow their users to
# change the 16 so-called "ANSI" colors. It is also possible on some platforms
# to change some or all of the 256 colors in the xterm palette. Don't take
# anything for granted.
# * When used against a light background, strong colors work better than muted
# ones. Light or dark doesn't really matters. Also, it is harder to discriminate
# between two similar colors on a light background.
# * Both strong and muted colors work well against a dark background. It is also
# easier to work with similar colors, but dark colors don't work at all.
# * Use as many text samples as possible. String-heavy languages may look completely
# different than keyword-heavy ones. This can have an impact on the usability
# of your colorscheme.
# * Most terminal emulators and terminal multiplexers currently in use on unix-like
# systems support 256 colors but they almost always default to a '$TERM' that tells
# Vim otherwise. Your users will need to make sure their terminal emulator/multiplexer
# is correctly set up if they want to enjoy the best possible experience.
# Many thanks to Barry Arthur (https://github.com/dahu) for the original idea.
# You don't need to edit anything beyond this line.
