## What it is
A PHP library that extracts the most representative colors from an image, building a color palette sorted by pixel count. It handles transparency by blending against a configurable background color.

## Use cases
- extract dominant colors from an image in php
- generate a color palette from a png or jpeg
- get the most used colors in a picture
- pick representative colors for thumbnails or theme generation
- handle transparent pixels when extracting image colors

## When to choose
- you need dominant or representative colors from images in a PHP project
- you want a simple Composer-installable palette extractor with transparency handling

## When to avoid
- you need advanced color quantization or perceptual color spaces beyond basic extraction
- you are not working in PHP

## Facets
- artifact type: library
- maturity: stable
- function: image-processing
- domain: image-processing, developer-tools
- platform: php
- tags: color-palette, dominant-colors, gd, composer
