17. What is color scheme?
18. Before learning about color schemes,
 we need to know about Syntax and Highlighting
19. Syntax Syntax extracts syntax groups for highlighting help.txt For Vim version 8.0. Last change: 2016 Sep 12 VIM - main help file k Move around: Use the cursor keys, or "h" to go left, h l "j" to go down, "k" to go up, "l" to go right. j Close this window: Use ":q<Enter>". Get out of Vim: Use ":qa!<Enter>" (careful, all changes are lost!). Jump to a subject: Position the cursor on a tag (e.g. bars) and hit CTRL-]. With the mouse: ":set mouse=a" to enable the mouse (in xterm or GUI). Double-click the left mouse button on a tag, e.g. bars. Jump back: Type CTRL-T or CTRL-O. Repeat to go further back. Get specific help: It is possible to go directly to whatever you want help on, by giving an argument to the :help command. Prepend something to specify the context: help-context WHAT PREPEND EXAMPLE Normal mode command :help x :help
20. help.txt For Vim version 8.0. Last change: 2016 Sep 12 VIM - main help file k Move around: Use the cursor keys, or "h" to go left, h l "j" to go down, "k" to go up, "l" to go right. j Close this window: Use ":q<Enter>".

21. Syntax file * Syntax is defined by syntax file * Syntax file extracts syntax groups from buffer using pattern and some other rules ... " Group name Pattern etc. " ------------------ ---------------------------------------- syn match helpSpecial "\<N\>" syn match helpHyperTextJump "\\\@<!|[^"*|]\+|" contains=helpBar syn match helpHyperTextEntry "\*[^"*|]\+\*\s"he=e-1 contains=helpStar ... Syntax file: $VIMRUNTIME/syntax/help.vim
22. Highlighting Highlighting is appearance information for syntax groups help.txt For Vim version 8.0.

24. Highlighting and for other UI components (= default highlighting groups) CursorLineNr Cursor LineNr VertSplit StatusLineNC PmenuThumb Pmenu StatusLine
25. Type :hi in your Vim!
26. These are highlighting groups for your current buffer-----
27. So, color scheme is...

29. Color scheme is a set of highlighting definitions for syntax groups and other UI components
30. How to create a color scheme?
31. guibg is for background color, guifg is for foreground color (for 24-bit color environments) Define highlighting groups Use :hi command :hi! Normal guibg=#161821 guifg=#c6c8d1 key value group name overwrite existing defs
32. ...and more highlighting groups ... hi! ColorColumn guibg=#1e2132 hi! CursorColumn guibg=#1e2132 hi! CursorLine guibg=#1e2132 hi! Comment guifg=#6b7089 hi! Constant guifg=#a093c7 hi!

33. Add CHARM before definitions " Support only 256 or full colors if !has('gui_running') && &t_Co < 256 finish endif " Set appropriate background set background=dark " Reset existing highlightings and syntax hi clear if exists('syntax_on') syntax reset endif " Name of the color scheme let g:colors_name = 'iceberg' hi! ... hi! ... hi! ...
34. That’s all! Very easy?
36. No... :(
37. There are still a lot of things to do * Cover whole highlighting groups * Consider coloration * Support 256 colors * Support various plugins * ...
38. Creating a color scheme is easy But, creating a lovely one is not easy
39. How to create your lovely color scheme?
40. Case study: iceberg.vim http://cocopon.github.io/iceberg.vim/
41. First: decide a concept ╭──────────────────────────────╮ │ │ │ I want a dark, blue one... │ │ │ ╰──────────────────────────────╯ O o . ∩ ∩ (ɾωɾ)
42. ICEBERG!!
43. Q: Why decide a concept first?
44. A: It will help you to decide coloration in various aspects I will explain about that later
45. Development flow ╭─────────────────────────────────╮ │ Create a new file: iceberg.vim │ ╰─────────────────────────────────╯ │ ┌───────────────────▶│ │ ▼ │ ╭─────────────────────────────────╮ │ │ Add some definitions by :hi │ │ ╰─────────────────────────────────╯ │ │ │ │ │ ▼ │ ╭─────────────────────────────────╮ │ │ Save, :source % to apply them │ │ ╰─────────────────────────────────╯ │ │ └────────────────────┘
46. Let’s start from here * Run your Vim without any color scheme * And then :hi clear to clear existing highlightings
47. Pick default bg/fg color Background #161821 Foreground #c6c8d1
48. Apply default bg/fg color to groups Normal and EndOfBuffer is for them Normal EndOfBuffer
49. hi! Normal guibg=#161821 guifg=#c6c8d1 hi! EndOfBuffer guibg=#161821 guifg=#c6c8d1
50. Before After
51. Pick representative colors #e27878 #e2a478 #b4be82 #89b8c2 #84a0c6 #a093c7 It will help you to keep an ambience of the color scheme Default background color: #161821
52. BTW, highlighting has a link structure Use :hi link to link a group to another group :hi! link jsFunction Function ╭────────────╮ ╭──────────╮ ╭───────────────╮ │ jsFunction │ ─▶ │ Function │ ─▶ ··· ─▶ │ guifg=#e2a478 │ ╰────────────╯ ╰──────────╯ ╰───────────────╯
53. Top level groups are called “preferred group” (Filetype etc.) ┊ Minor ┊ Preferred ┊ ┊ ╭─────────────╮ ┊ ╭─────────────╮ ┊ ╭────────────╮ │ jsFunction │──────▶│ Function │──────▶│ Identifier │ ╰─────────────╯ ┊ ╰─────────────╯ ┊ ╰────────────╯ ┊ ┊ ╭─────────────╮ ┊ ╭─────────────╮ ┊ ╭────────────╮ │ ··· │──────▶│ String │─┬────▶│ Constant │ │ ··· │──────▶│ Character │─┤ ┊ ╰────────────╯ │ ··· │──────▶│ Number │─┤ ┊ │ ··· │──────▶│ ┊ │ ┊ ┊ ╰─────────────╯ ┊ ╰─────────────╯ ┊ ┊ ┊ ╭─────────────╮ ┊ ╭─────────────╮ ┊ ╭────────────╮ │ ··· │──────▶│ Conditional │─┬────▶│ Statement │ │ ··· │──────▶│ Repeat │─┤ ┊ ╰────────────╯ │ ··· │──────▶│ Label │─┤ ┊ │ ··· │──────▶│ ┊ │ ┊ ┊ ╰───────── ───╯ ┊ ╰─────────────╯ ┊ :help group-name to see the list of the groups
54. Apply colors to preferred groups ██ #e27878 ─▶ Error ██ #e2a478 ─▶ Function (minor group but frequently used) ██ #b4be82 ─▶ PreProc, Special ██ #89b8c2 ─▶ Identifier, Type ██ #84a0c6 ─▶ Statement ██ #a093c7 ─▶ Constant They make an ambience of your color scheme
55. Before Looks better! After
56. TIPS: Use HSB/HSL color model to choose colors GIMP, Inkscape, Photoshop, Illustrator ... some kind of graphics software has the feature It makes easy to create a harmonious palette
57. Change only hue to create initial colors Primary HSB(215°, 33%, 78%) Hue: 0° Hue: 30° Hue: 90° Hue: 180° Hue: 250° ─▶ Fix saturation and brightness at first, and fine-tune them later
58. Q: Why create a color palette first?
59. A: It will prevent the number of colors from explodingly increasing

61. So if you select a color for each group, a huge amount of similar colors will be generated It will cause many bad effects: increasing maintenance cost, breaking an ambiance, etc.
62. highlight-groups highlight-default These are the default highlighting groups. These groups are used by the 'highlight' option default. Note that the highlighting depends on the value of 'background'. You can see the current settings with the ":highlight" command. hl-ColorColumn ColorColumn used for the columns set with 'colorcolumn' hl-Conceal Conceal placeholder characters substituted for concealed text (see 'conceallevel') hl-Cursor Cursor the character under the cursor hl-CursorIM CursorIM like Cursor, but used when in IME mode CursorIM hl-CursorColumn CursorColumn the screen column that the cursor is in when 'cursorcolumn' is set Define colors for default highlighting groups :help highlight-groups to see the list for them :help highlight-groups
63. Pick colors that is close in hue They will make the ambience stronger Background #161821 Hue: 229° Foreground #c6c8d1 Hue: 229° LineNr (bg) #1e2132 Hue: 231° LineNr (fg) #444b71 Hue: 231° StatusLine (bg) #818596 Hue: 229°
64. Before After Ah...lovely... <3
65. Useful tools to cover all highlighting groups $VIMRUNTIME/syntax/hitest.vim colorswatch.vim
66. Create a color palette first, and then apply it to each groups It will help you to keep an ambience of the color scheme
67. Make your color scheme more lovely
68. Strategy Increase positive features and reduce negative features ╭───────────────────────────────────╮ ╭───────────────────────────────────╮ │ Increasing positive features │ │ Reducing negative features │ │ will increase fan of your scheme │ │ will decrease abandonment rate │ │ ───────────────────────────────── │ │ ───────────────────────────────── │ │ · Support various filetypes │ & │ · Support 256 colors │ │ · Support famous plugins │ │ · Think about warning color │ │ · Add some identities │ │ · Think about color vision │ │ · Highlight only important groups │ │ │ ╰───────────────────────────────────╯ ╰───────────────────────────────────╯
69. Increase positive features
70. Adjust coloration for various filetypes CSS XML TypeScript
71. CSS XML TypeScript Is this coloration cool?
72. Too much orange...?
73. ...more blue! Remember the concept
74. Use syntax-specific groups Syntax-specific groups are defined by each syntax files vimAbb vimAddress vimAugroup vimAugroupError vimAugroupKey vimAugroupSyncA vimAuHighlight vimAuSyntax vimAutoCmd vimAutoCmdOpt vimAutoCmdSfxList vimAutoCmdSpace vimAutoEvent vimAutoEventList vimAutoSet vimBehave xmlAttrib xmlAttribPunct xmlCdata xmlCdataCdata xmlCdataEnd xmlCdataStart xmlComment xmlCommentError xmlCommentPart xmlCommentStart xmlDocType xmlDocTypeDecl xmlDocTypeKeyword xmlEndTag xmlEntity xmlEntityPunct cssAnimationAttr cssAnimationProp cssAttr cssAttrComma cssAttributeSelector cssAttrRegion cssAuralAttr cssAuralProp cssBackgroundAttr cssBackgroundProp cssBorderAttr cssBorderProp cssBoxAttr cssBoxProp cssBraceError cssBraces $VIMRUNTIME/syntax/css.vim $VIMRUNTIME/syntax/vim.vim $VIMRUNTIME/syntax/xml.vim ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... $VIMRUNTIME/sy

76. Result Before (much orange) After
77. TIPS: Looking for the unknown highlighting group How about my plugins (pgmnt.vim and colorswatch.vim) First, move cursor to the position that you want to know the highlight info
78. TIPS: Looking for the unknown highlighting group How about my plugins (pgmnt.vim and colorswatch.vim) And then execute :PgmntDevInspect
79. TIPS: Looking for the unknown highlighting group How about my plugins (pgmnt.vim and colorswatch.vim) It will print the link structure of the highlight group
80. Support famous plugins e.g. EasyMotion Before After
81. Support famous plugins e.g. lightline.vim Before After
82. Highlight only important groups “this” is important keyword in JavaScript but hard to find (much orange...)
83. Highlight only important groups Less orange, easy to find “this”
84. Add some identities ↓ CREVASSE
85. Add some identities ↑ CREVASSE
86. Reduce negative features
87. Support 256 (cterm) colors :hi! Normal ctermbg=234 ctermfg=252 ctermbg is for background color, ctermfg is for foreground color
88. Support 256 (cterm) colors Use color chart to picking colors https://commons.wikimedia.org/ wiki/File:Xterm_256color_chart.svg
89. Before After Support 256 (cterm) colors
90. Think about warning color Reddish colors are usually used as warning color Destructive options on iOS ISO 3864 DANGER WARNING CAUTION https://developer.apple.com/ios/human-interface-guidelines/views/action-sheets/ https://www.iso.org/obp/ui/#iso:std:iso:3864:-1:en
91. Iceberg refrains from using red colors Only uses them for error, warning, and other appropriate elements
92. Think about color visions Not everyone have the same color visions Normal Protanopia Dark red should not be used on dark background
93. Contrast colors by brightness, not hue Normal Red Normal Red Normal Red Normal Red ↓ ↓
94. And...
95. Learn from great forerunners
96. To make your color scheme more lovely, increase positive features and reduce negative features And... learn from great forerunners
97. How to find great forerunners?
98. Long ago: VIM Color Scheme Test https://web-beta.archive.org/web/*/http://vimcolorschemetest.googlecode.com/
99. Recently: vimcolors.com http://vimcolors.com/
100. But I have some frustrations... ╭──────────────────────────────────────────╮ │ │ │ What really I want to do is not │ │ to see a huge amount of color schemes, │ │ but finding the best one! │ │ │ ╰──────────────────────────────────────────╯ O o . ∩ ∩ (ɾωɾ)
101. So I developed a new web app
102. colorswat.ch http://colorswat.ch/vim/
103. Sorting by GitHub stars
104. More accurate preview vimcolors.com Tab/EOL characters, line number, cursor, cursorline, etc. colorswat.ch
105. References You can see the source of color schemes
106. References: Example onedark is based on FlatColor that is based on pencil onedark FlatColor pencil ◀┄┄ ◀┄┄
107. And... mobile friendly ;)
108. colorswat.ch is useful to find great forerunners

112. Extracting highlighting data Using colorswatch.vim to extract all highlighting data
113. Q: So, how does colorswat.ch find color schemes?
114. A: My power of love
115. Source of color schemes Web/Twitter search Recommendation from users (colorswat.ch)
116. Roadmap * Diff mode support * Missing components: StatusLine, VirtSplit, etc. * Other editors support (Atom, VS Code, ...) * Re-implemented server in Go ʕ◔ϖ◔ʔ * Author page * ...
117. colorswat.ch is made with my love
118. Conclusion
119. To create your lovely color scheme,
120. Decide a concept

128. Appendix
129. Use HSL color model in Vim script pgmnt.vim provides the feature ··· let hue_red = 0 let hue_orange = 25 let hue_green = 70 ··· let g_blue = pgmnt#color#hsl(hue_blue, 0.37, 0.65) let g_green = pgmnt#color#hsl(hue_green, 0.32, 0.63) let g_lblue = pgmnt#color#hsl(hue_lblue, 0.32, 0.65) ··· If you interested, see iceberg.vim/src/ for the usage case
