README 文档

README

PHP color toolkit for conversion and normalization across common color models.

💖 Part of the tc-lib-pdf / TCPDF ecosystem (100M+ installs). Sponsor its maintenance →

Overview

tc-lib-color provides utilities for parsing, converting, and formatting color values used in web and PDF rendering pipelines.

The library is designed to centralize color logic so applications avoid ad-hoc conversion code and rounding drift across modules. It provides a consistent normalization layer that helps keep visual output aligned between browser previews and final PDF rendering.
