## What it is
iro.js is a modular, dependency-free color picker widget for JavaScript built with SVG, supporting hex, RGB, HSV, HSL, and kelvin color formats. It offers composable pre-built UI components, multi-color selection for harmonies, and a small ~9kb bundle.

## Use cases
- add a color picker to a web form
- pick colors for smart home RGB LED lighting controls
- select color harmonies and themes with multiple swatches
- convert colors between hex, RGB, HSV, and HSL in the browser
- build a custom-styled color picker without jQuery or CSS files

## When to choose
- you need a lightweight, zero-dependency color picker for any JS app or framework
- you want multi-color selection and multiple color format support
- you need a picker for RGB lighting or smart home UIs
- you want a single-script widget with no extra CSS or images

## When to avoid
- you need a project under active development - it is officially on hiatus
- you need native platform color pickers or mobile-specific UI
- you need canvas-based or heavily themable pickers beyond the provided SVG components

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, frontend-framework
- domain: web-development, frontend, graphics
- platform: browser
- tags: color-picker, svg, no-dependencies, color-formats, widget, javascript, nodejs
