## What it is
Open Color is an open-source color scheme optimized for UI design, providing 13 hues with 10 brightness steps each. It ships as variables for CSS, Sass, Less, Stylus, Tailwind, JSON, and design tool palettes like Sketch, Figma, and Photoshop.

## Use cases
- pick a consistent color palette for a web UI
- use color variables in Sass or Less stylesheets
- import a color scheme into Tailwind CSS
- get swatches for Photoshop, Sketch, or Figma
- find harmonious background and font colors for an app
- use a perceptually consistent brightness scale across hues

## When to choose
- you need a general-purpose, well-tested UI color palette
- you want the same colors across CSS preprocessors and design tools
- you want a neutral scheme rather than a brand identity color

## When to avoid
- you need a unique brand identity color scheme, since colors may change
- you need highly customized or brand-specific hues
- your project requires a design system beyond just colors

## Facets
- artifact type: dataset
- maturity: stable
- function: ui-components, css-framework, theme
- domain: web-design, frontend, web-development
- platform: cross-platform
- tags: color-scheme, design-system, scss, less, stylus, tailwind, swatches, figma, sketch, web-server
