## Description

Chameleon is a color framework for Swift and Objective-C applications, providing a toolkit for managing dynamic palettes, gradient libraries, and hexadecimal conversions. It functions as a system for creating harmonious color schemes and calculating contrasting text colors based on background luminance.

The project includes an image color extractor that analyzes images to generate matching color schemes or calculate average colors for user interfaces. It also features a gradient color library for creating and applying smooth transitions to backgrounds and text elements.

The framework covers broader color management capabilities, including hexadecimal string parsing, random color generation, and luminance adjustments. It provides utilities for calculating accessibility contrast and applying global themes across multiple interface views.
