InuProt

A two-variant colour scheme pack, published for Visual Studio Code and Sublime Text.

Who this is for

InuProt is tuned for readers with red-green color vision deficiencies (red-green color blindness), specifically:

• Protanomaly / protanopia — red-weak or red-blind vision
• Deuteranomaly / deuteranopia — green-weak or green-blind vision
• Anyone whose eyes find saturated neon greens painful or hard to read

In typical syntax themes the keyword green and the control-flow / string / number orange sit close in both hue and luminance, so they merge for these readers. InuProt fixes that pairing: the green ramp is dimmed away from the orange in the dark variant, and the light variant uses a green-tinted chrome that stays distinguishable.

If you searched for colorblind theme, protanopia theme, red-green colorblind color scheme, high-contrast accessible VS Code theme, or accessible Sublime Text theme — this project is for you.

Keywords: colorblind, colorblind-friendly, protanopia, protanomaly, deuteranopia, deuteranomaly, red-green color vision deficiency, accessible, accessibility, high contrast, VS Code theme, Sublime Text color scheme.

Variants

Variant	Surface	Origins
InuProt Dark	black + ink-green	Forked from Human High Contrast by Tom Hall, with the green ramp dimmed for better separation from the orange control-flow / string color.
InuProt Light	soft green tint	Forked from GitHub Light Colorblind (Beta) (primer/github-vscode-theme, MIT), with the editor surface retinted to #edf3eb and chrome to #e6eee4; syntax token colors are inherited unchanged (the upstream theme is already tuned for colorblind accessibility).

About the name. Prot stands for Protanomaly (red-weak color vision deficiency). People with protanomaly — and the more general category of deuteranomaly / red-green color blindness — have trouble distinguishing green from orange/red. Two of the most important colors in almost every code syntax theme are green (keywords) and orange/yellow (control-flow + strings + numbers). When those two sit close together in hue and luminance, they merge for protanopic readers. InuProt exists specifically to separate them: the Dark variant dims the green ramp away from the orange, and the Light variant uses a soft green-tinted chrome that stays distinguishable. The accompanying Inu prefix is the Japanese 犬 ("dog") — a small nod to its🐾 pedigree (an Inu watches over what it keeps close).

What changed from upstream?

InuProt Dark (from Human High Contrast)

Only the green ramp was retuned, to lower its luminance away from the orange/yellow control-flow + string color. Source changes are in source/changes-dark.md; in short:

Token role	Before	After
keywords / cursor / button	#00FF00	#00AA00
function names / gutter added	#00EE00	#009900
git untracked / hint	#00DD00	#008800

Everything else (UI chrome, terminal ANSI, token rules) is unchanged.

InuProt Light (from GitHub Light Colorblind)

Only background surfaces were retinted to a soft green. Syntax token colors are inherited unchanged from GitHub Light Colorblind. Source changes are in source/changes-light.md; in short:

Surface	Before	After
editor / gutter / active tab	#FFFFFF	#edf3eb
sideBar / activityBar / statusBar / panel / titleBar / tab inactive / widgets	#FAFAFD	#e6eee4
sticky hover / no-folder status	#F0F0F3	#dfe7dd

input.background and dropdown.background stay #FFFFFF so white controls still read cleanly on the green chrome.

Install

Visual Studio Code

code --install-extension ./vscode/inuprot-1.0.5.vsix

Or use the Command Palette → Preferences: Color Theme → InuProt Dark or InuProt Light.

Sublime Text

Copy the two files in sublime/ into your Packages/User directory:

• sublime/InuProt Dark.sublime-color-scheme
• sublime/InuProt Light.sublime-color-scheme
• (legacy) sublime/InuProt Dark.tmTheme / sublime/InuProt Light.tmTheme

Then in Preferences.sublime-settings:

{
  "color_scheme": "InuProt Dark.sublime-color-scheme",
  "dark_color_scheme": "InuProt Dark.sublime-color-scheme",
  "light_color_scheme": "InuProt Light.sublime-color-scheme",
}
