## What it is
uchū is an OKLCH-based color palette distributed as CSS custom properties (with Sass support) for web projects. It provides expanded and reduced palettes across gray, red, pink, purple, blue, green, yellow, and orange scales.

## Use cases
- find a modern color palette for a website
- use OKLCH colors in CSS
- theme an app with CSS variables
- get consistent color scales for UI design
- add a dark-mode-friendly palette to a project
- use a color palette in Svelte/SvelteKit

## When to choose
- you want a ready-made, perceptually uniform OKLCH palette
- you prefer CSS custom properties or Sass variables
- you want a permissive (Unlicense) color scheme with no dependencies

## When to avoid
- you need RGB/HSL or other color space formats
- you need a full component library or design system beyond colors
- you need highly customizable palette generation

## Facets
- artifact type: library
- maturity: stable
- function: css-framework, theme
- domain: web-development, frontend, web-design
- platform: browser, cross-platform
- tags: color-palette, oklch, css-variables, design-system, sass, dark-mode, web-server
