Neon DSH Themes

English · 简体中文

Three neon palettes for DeepSeek Harness (DSH) — cyan, pink and yellow — in one row in settings.

This is a small DeepSeek Harness (DSH) plugin: it adds a Theme colors row under Appearance in Settings → General, with three swatches you click to switch. No theme panel, import/export, or wallpapers.

Colors only: neutral scale + accent + semantic colors + borders + syntax highlighting.

The three palettes

ID	Name	Accent (dark)	Accent (light)	Notes
neon-cyan	Neon Cyan	#54F5FF	#007A87	Arctic neon cyan on a cool gunmetal base
neon-pink	Neon Pink	#FF94B8	#B03A64	Electric neon pink
neon-yellow	Neon Yellow	#E6FF40	#6E7C00	Acid neon yellow

Shared base: in dark appearance the neutral scale runs from #F2F5F7 down to #0A0B0D (a near-black cool base, not pure black), and borders carry a hint of the palette color (alpha 7). Light appearance has its own near-white base and coexists with DSH's built-in Appearance switch — Appearance chooses dark / light / follow-system, Theme colors only picks which of the three palettes is active.

How it works

• themes/*.json is the single source of truth: each palette stores only seeds (neutral endpoints, accent/green/amber/red, border, shiki).
• scripts/build-client.mjs expands the seeds into CSS variables with the same algorithm as the DSH presets and inlines them into lib/client.js.
• Surface tokens get a 5–14% wash of the accent (SURFACE_TINTS: sidebar, selected rows, input, bubble, settings card, hover); text and ramps stay neutral.
• The client plugin registers a row in the settings.general.item slot (order 10.5, right after Appearance). Selecting a palette adds data-neon-palette="<id>" to <html>, and the static stylesheet switches between light and dark based on data-ds-dark-theme.
• The selection is stored under dsh-neon-palette in localStorage and survives a refresh; with no selection, everything returns to the DSH defaults.

Install / develop

git clone git@github.com:iShawnWang/dsh-theme-neon.git
cd dsh-theme-neon
npm run build        # generate lib/client.js from themes/*.json
npm run check        # verify lib/client.js is in sync with themes/*.json

Mount the repo as a file: dependency in your DSH profile:

# ~/.dsh/profiles/desktop/package.json
#   dependencies: { "dsh-theme-neon": "file:/path/to/dsh-theme-neon" }
#   dsh.profile.bundles: [ ..., "dsh-theme-neon" ]
pnpm install --dir ~/.dsh/profiles/desktop

Or let DSH install the plugin directly from GitHub:

dsh plugin add github:iShawnWang/dsh-theme-neon

Refresh the DSH window (restart if needed). Open Settings → General and you will find Theme colors below Appearance: the Neon Cyan / Neon Pink / Neon Yellow swatches — click one to switch; Appearance still controls dark / light.

To change colors, edit themes/*.json and run npm run build; the plugin picks it up when DSH reloads it.

Layout

themes/                  seed JSON for the three palettes
scripts/build-client.mjs seeds → CSS variables → lib/client.js
lib/index.js             host half (empty; keeps the profile bundle structure valid)
lib/client.template.js   client plugin source (with placeholders)
lib/client.js            generated, committed, loaded by DSH directly
cordis.patch.yml         profile patch that adds the plugin to the bundle list
assets/icon-180.png      market card icon
assets/screenshots/      settings screenshots (three dark + one light)
screenshots.json         market screenshot manifest, paths relative to repo root

The original Chrome theme (the Chrome Web Store release) lives in iShawnWang/chrome-theme-neon.
