## What it is
Spectrum is a lightweight, image-free JavaScript color picker built as a jQuery plugin, using CSS gradients for cross-browser rendering. It supports a wide range of customization options, mobile touch input, and can act as a polyfill for the HTML5 input[type=color] element.

## Use cases
- add a color picker to a web form
- polyfill input[type=color] in older browsers
- let users pick colors on mobile and desktop
- embed a colorpicker in a devtools-like tool
- customize and skin a colorpicker with CSS

## When to choose
- you need a small, dependency-light colorpicker with no images
- you want a jQuery-based picker with a simple API
- you need touch-friendly mobile support

## When to avoid
- you need a framework-native React/Vue color picker component
- your project no longer uses jQuery
- you need actively developed features or recent bug fixes

## Facets

- maturity: maintenance
- function: ui-components, frontend-framework
- domain: web-development, frontend
