App & OS-UI themes

Application/platform-level CVD themes

Whole products shipping first-party colorblind themes (not editor plugins — the app itself). Verified via merged PRs and source files:

Grafana is the flagship here — the first major observability platform with built-in CVD themes. The four theme files (deuteranopia_protanopia_{dark,light}.json, tritanopia_{dark,light}.json) override the semantic signal colors: dark success #2EC4B6 (teal) / error #FF7A18 (orange) / warning #FFF899; light success #006F7A / error #FF9900 / warning #FFEE52. The viz palette (fieldColor.ts, PaletteColorblind mode) is Wong (2011) / Okabe–Ito verbatim with black/white for theme-adaptive contrast — the source comment cites Wong directly and states all 8 colors are validated as mutually distinguishable under all three dichromacies.

coder/coder’s darkProtanDeuter/roles.ts is unusually well-documented: “Protanopia and deuteranopia compress the red/green channel, so semantic good/bad pairs that rely on green vs red need a different axis. We shift destructive states onto a vermilion/orange hue (Tailwind orange scale, inspired by the Okabe-Ito CVD-safe scheme), positive/active states onto sky-blue, and warning onto fuchsia so it does not collide with destructive states on the orange axis.”

20 more application-level CVD themes (merged, primary-source verified)

A GitHub merged-PR sweep across observability, code hosts, git GUIs, chat, note apps, CAD/3D printing, game clients, and mobile surfaced these (full extraction notes in .research/09-app-level.md):

Three patterns across all app-level CVD themes:

1. Okabe-Ito anchoring is dominant — iamb, portico, OpenFront, OSC_Workout, deepinv, mai-tutor, RustySNES all cite or embed the eight canonical hexes. It is the de-facto standard.
2. Blue/orange is the universal diff/status swap — Gitea, SimpleCov, GitButler, plannotator, tuicr all converge on GitHub’s #58a6ff/#f0883e (dark) or Okabe-Ito’s #0072B2/#D55E00.
3. Per-deficiency variants are emerging as the highest-fidelity approach — Grafana (4 themes), Talishar (3 palettes), Gitea (2 CSS families), steady (5 modes) ship distinct palettes per CVD type rather than one “universal” palette, matching modus/ef-themes in editor space.

Verified negatives (no first-party CVD theme as of 2026-11-05): DataDog, Prometheus, Kibana, GitLab (first-party — the third-party gitlab-colorblind extension covers it), Bitbucket, Linear, Asana, Monday, Jira, Slack/Discord/Teams/Element/Zulip, Obsidian/Logseq/Joplin (first-party), Godot, Unity, Bitwarden, Anki, Home Assistant, Jellyfin, FreeCAD, KiCad, ArgoCD, k9s, Swagger UI.

First-party product themes (Wireshark, Insomnia, and more)

Including the oldest app-level CVD theme found anywhere (Jenkins, 2012).

Wireshark ships Protanopia & Deuteranopia and Tritan themes (dark + light) — Okabe-Ito/Wong verbatim, gated by test/suite_theme.py which checks every token stays distinguishable under each listed deficiency. The first major network-analysis tool with first-party CVD themes. (themes dir, GPL-2.0)

Insomnia (Kong) shipped a Dark Colorblind core theme in 2021 (PR #4081) — days after GitHub’s own colorblind beta, and the only API client with a first-party CVD theme. HTTP-method colors swap to blue/orange: POST/200 #0080FF, DELETE #CC5500 (burnt orange).

Kiro ships a built-in “Color-blind safe” theme pair (dark+light) with a simulation test that measures every status pair under all three dichromacies; Okabe-Ito status hues. (PR #24480)

Google’s gemini-cli ships github-dark-colorblind / github-light-colorblind built-ins — Primer colorblind tokens verbatim in a Google first-party CLI. (PR #15504, Apache-2.0)

More product themes:

Verified empty surfaces (checked and confirmed to have no CVD theme): spicetify/Spotify, btop/htop/glances, waybar/polybar/i3/sway, database GUIs (pgAdmin/DBeaver/phpMyAdmin), Postman/ Hoppscotch/Bruno, e-readers (Zathura/KOReader/calibre/Sumatra), email clients (Thunderbird/Mutt), TradingView/finance terminals, Android launchers, GIMP/Krita/darktable. The Wordle-clone long tail (dozens of near-identical student clones) is excluded as noise.

Pitaya Smoothie — the only CVD-designed JupyterLab theme

Tania Allard / Quansight Labs (jupyterlab-accessible-themes, upstream trallard/pitaya_smoothie, BSD-3). “The colour choices… were made taking into consideration accessibility for those with colourblindness — by default the theme is suitable for multiple types of colourblindness, no settings tweaking required.” The README embeds protanopia/deuteranopia/tritanopia simulations and a WCAG AAA contrast grid. Teal/pink axis with yellow warnings: brand teal #1abec2, accent pink #f25a92, warn yellow #fad000, periwinkle #7998f2, lilac #a56cf5, orange #f38672, bg indigo #181036. Dark only; uses the Atkinson Hyperlegible font.

(Also in the Jupyter ecosystem: jupyterlab_colorblind is a Machado-2009 simulator extension for previewing your own plots under CVD — tooling, not a theme.)

Lx Deep Sea — a KDE Plasma color scheme for red-green CVD

lx21, 2022 (store.kde.org/p/1711107, GPLv3). The only CVD-labelled Plasma color scheme found; the store front is bot-walled but the raw .colors file was fetched via the OCS API. Author’s claim: “high contrasts and at the same time eyefriendly and suitable for red-green colorblindness.” Dark; blue-tinted neutrals, blue links #508ED8, neutral #55AAFF.

Honest caveat: its Negative #FF1B13 (pure red) vs Positive #57CF1F (green) still differ mainly by hue — the simulation strip shows them collapsing toward each other under deuteranopia/protanopia. It leans on brightness/saturation separation rather than the orange↔blue hue remap the stronger entries use. Included as the sole KDE desktop entry, with that limitation noted.

Slack, Discord, Teams

• Slack: Opo ships the only published Slack CVD palette — a custom-theme import string (#fbf8f2, #005ccc, #002c85, #a75000…) built from its build-time-CVD-checked blue/orange axis (dist/slack/opo-light.txt). Slack’s own “accessible theme” still publishes no hexes.
• Discord: dalton-discord (MIT) claims Deutan intent with a blue #2b7df0 accent — but its presence dots keep hard #00FF00/#FF0000, the canonical deutan confusion pair. Medium evidence; self-defeating status colors.
• Teams: genuine negative — no user theme format with published palettes; only an unpublished “high contrast” mode.

The OS-level reality: filters, not themes

No operating system ships a built-in CVD color scheme. KDE (Breeze ships Classic/Dark/Light only), GNOME (Adwaita + high-contrast only), and Windows (four high-contrast presets) all rely on screen-level daltonization/color-correction filters instead:

• KDE Plasma 6 — KWin “Color Blindness Correction” compositor effect (protan/deutan/tritan + monochrome), a real-time LMS-space daltonization shader applied to everything on screen. docs · source
• GNOME — third-party “Colorblind Filters” shell extension (screen shader).
• Windows 10/11 — Color Filters (protanopia/deuteranopia/tritanopia correction).
• macOS/iOS — Color Filters in Accessibility settings.

These correct the whole display rather than re-theming any app, which is why per-app CVD themes (everything above) remain necessary: a global filter can’t fix a palette that was never designed to survive it, and it shifts all colors including the ones already safe.
