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