Tailwind CSS Shades

Tailwind CSS Shades

Generate a full Tailwind CSS color palette (50 to 950) from any color, right in your editor. Works with Tailwind v4, v3, v2 and v1.

VS Code Marketplace · Open VSX (Cursor, Windsurf, VSCodium)

Also as a command line tool and an MCP server for AI agents, with the same palettes. Try it in the browser: tailwindshades.bourhaouta.com.

Usage

1. Select a color, or just put the cursor on it: #db4d53, rgb(…), hsl(…), oklch(…) or a CSS color name.
2. Press Cmd+K Cmd+G (macOS) or Ctrl+K Ctrl+G, or run Tailwind Shades: Generate color palette from the Command Palette.
3. Pick a name. The closest Tailwind color is suggested; type your own (like brand) to keep Tailwind's color too.

With no color under the cursor, the extension asks you for one.

Tailwind v4 (CSS file)

@theme {
  --color-brand-50: oklch(97.1% 0.01 13.669);
  --color-brand-100: oklch(93.2% 0.024 14.006);
  --color-brand-200: oklch(87.7% 0.046 14.623);
  --color-brand-300: oklch(79.5% 0.085 15.86);
  --color-brand-400: oklch(68.7% 0.143 18.505);
  --color-brand-500: oklch(61.6% 0.177 21.62);
  --color-brand-600: oklch(56% 0.183 23.614);
  --color-brand-700: oklch(49.2% 0.159 23.807);
  --color-brand-800: oklch(43.6% 0.133 23.188);
  --color-brand-900: oklch(39.2% 0.106 22.012);
  --color-brand-950: oklch(25.8% 0.069 22.331);
}

Already inside an @theme { … } block? Only the variables are added.

Tailwind v3 (tailwind.config.js)

brand: {
  50: '#fdf2f3',
  100: '#fae2e3',
  200: '#f6c9cc',
  300: '#efa5a9',
  400: '#e7757a',
  500: '#db4d53',
  600: '#ca373c',
  700: '#aa2c30',
  800: '#8d272b',
  900: '#772528',
  950: '#411012',
},

How the shades are made

The palette follows Tailwind's own colors instead of simply mixing with white and black:

• It finds the Tailwind color closest to yours, and copies how that color's lightness, saturation and hue change from light to dark.
• Your color stays exactly as it is, at the shade where it fits best. A light color can become 200, not always 500.
• The math happens in OKLCH, the color space Tailwind v4 uses, so the steps look even to the eye.

Tailwind versions

The version is detected from your project, most reliable source first:

1. The closest package.json with a tailwindcss dependency
2. The current CSS file: @import "tailwindcss", @theme, @utility, @plugin → v4; @tailwind base; → v3
3. A tailwind.config.js (or .ts, .cjs, .mjs) in the project → v3
4. Other CSS files in the project, with the same hints as step 2

If nothing is found, v4 is used. The status bar tells you which version was used and why, e.g. v3 from tailwind.config.js.

Each version uses its own default palette as the reference, so a v1 palette looks like v1 colors.

Commands

Settings

Command line

The same palettes, without an editor:

npx tailwindshades-cli "#db4d53" --name brand

The palette goes to stdout, so you can add it to a file: npx tailwindshades-cli db4d53 -o css >> colors.css. More in the package README.

Use it with AI agents

AI coding agents often guess Tailwind shades, or add one --color-brand line instead of a palette. The tailwindshades-mcp server gives them five tools:

• generate_palette: the same palette code as the extension, for the project's Tailwind version
• find_closest_tailwind_color: the Tailwind class closest to a color (e.g. #db4d53 → red-500), and whether the difference is visible
• get_tailwind_palette: Tailwind's own default colors, exactly as Tailwind defines them (e.g. slate-500), so agents don't write them from memory
• list_tailwind_colors: the names of Tailwind's default colors for a version
• convert_color: any color to oklch() (what Tailwind v4 uses), hex and rgb

And an add_brand_color prompt, which Claude Code shows as a slash command.

Then ask things like "Add a brand color #db4d53 to my theme".

Remote, nothing to install: connect to https://tailwindshades.bourhaouta.com/mcp.

Claude Code

claude mcp add --transport http --scope user tailwindshades https://tailwindshades.bourhaouta.com/mcp

Cursor (~/.cursor/mcp.json, or .cursor/mcp.json in a project)

{
  "mcpServers": {
    "tailwindshades": { "url": "https://tailwindshades.bourhaouta.com/mcp" }
  }
}

VS Code (.vscode/mcp.json)

{
  "servers": {
    "tailwindshades": { "type": "http", "url": "https://tailwindshades.bourhaouta.com/mcp" }
  }
}

Local: run npx -y tailwindshades-mcp as a stdio server instead, for example claude mcp add --scope user tailwindshades -- npx -y tailwindshades-mcp. Setup for each agent is in the package README.

It's also in the MCP Registry as io.github.bourhaouta/tailwindshades, with both options.

Development

An npm workspace: the extension is at the root, the palette engine and CLI in packages/core, the MCP server in packages/mcp, and the website with the remote MCP endpoint (/mcp) in apps/web (npm run dev -w apps/web).

npm install
npm run check   # type check + tests
npm run build   # bundle the extension to dist/

Press F5 in VS Code to try the extension in a new window. After upgrading a tailwindcss dev dependency, run npm run palette to refresh the reference palettes. After an engine change, node media/demo/record.mjs re-records the demo GIF (see the file for setup).
