Node-RED Color Picker

1.0.0 verified Mon Apr 27 auth: no javascript

A Node-RED node that stores a user-picked color in msg.color. Version 1.0.0, stable but limited to Node-RED ecosystem. Requires farbtastic dependency for the color picker UI. Not actively maintained.

Common errors

error Error: Cannot find module 'farbtastic' ↓

cause farbtastic is required but not installed

fix

Include farbtastic in your Node-RED environment, e.g., npm install farbtastic.

error Node type 'color' not found ↓

cause Node not installed correctly

fix

Install node-red-color via Manage Palette or npm in the Node-RED user directory.

error TypeError: Cannot read property 'color' of undefined ↓

cause Trying to use node outside Node-RED

fix

Only use within Node-RED, e.g., in a flow.

Warnings

gotcha farbtastic dependency is not included in npm install ↓

fix Manually ensure farbtastic is available (e.g., via <script> tag or bundling).

deprecated Node-RED nodes should be installed locally, not globally ↓

fix Use npm install node-red-color in the Node-RED user directory (e.g., ~/.node-red).

breaking No exports or JavaScript API; only works as Node-RED node ↓

fix Cannot be used outside Node-RED; it's a node for Node-RED flows.

Install

npm install node-red-color

yarn add node-red-color

pnpm add node-red-color

Imports

wrong
```
npm install -g node-red-color
```
correct
```
npm install node-red-color
```
Node-RED nodes should be installed locally or in the Node-RED user directory.
functionGlobalContext
```
// not applicable (Node-RED node)
```
Node-RED nodes are not imported via JavaScript; they are loaded by Node-RED at startup.
RED.nodes.registerType
wrong
```
require('node-red-color')
```
correct
```
module.exports = function(RED) { RED.nodes.registerType('color', ColorNode); }
```
Node-RED nodes must export a function that registers the node type with RED.

Quickstart

Install the node, add it to a flow, configure a color, deploy, and see the color in msg.color.

// In Node-RED, install via Manage Palette or npm:
// npm install node-red-color
// Then add a 'color' node from the palette.
// Configure: select a color in the picker.
// Deploy. The node sets msg.color to the chosen color string.
// Example flow:
[{"id":"1","type":"color","name":"My Color"}]
// Output: msg.color = "#ff0000" (example)
