## What it is
A Swift library that extracts the most dominant and prominent colors from UIImage and NSImage instances, in the style of iTunes artwork coloring. It returns a struct with background, primary, secondary, and detail colors, with configurable quality/performance tradeoffs.

## Use cases
- extract dominant colors from an image in swift
- dynamically theme ui background based on album artwork
- get primary and secondary colors from a photo like itunes
- generate background color matching an image in ios
- derive text colors that complement an image
- color analysis for uiimage on macos

## When to choose
- you need iTunes-style dynamic color theming for iOS, tvOS, or macOS apps
- you want a small, drop-in Swift file or CocoaPods/Carthage dependency
- you need a simple API with quality/performance tuning

## When to avoid
- you need cross-platform color extraction outside Apple platforms
- you need actively maintained code with recent updates
- you need advanced palette generation with many color clusters

## Facets
- artifact type: library
- maturity: maintenance
- function: image-processing, ui-components
- domain: image-processing, mobile-development, desktop-applications
- platform: -
- tags: uikit, color-extraction, dominant-colors, cocoapods, carthage, tvos, ios, macos, swift
