## Overview

The HEX to LCH Converter allows you to precisely transform hexadecimal color codes into the perceptually uniform LCH (Lightness, Chroma, Hue) color space, ensuring consistent color management across modern web and design projects.

## Inputs

- **HEX Input** (textarea): Enter HEX values, one per line: #ff0000 #00ff00 #ffffff #ff000080 #00ff0080 f00 0f0 00f f08 0f8
- **Output Format** (select)
- **Alpha Channel Handling** (select)
- **Custom Background Color** (color): Custom background color for alpha compositing (used when Custom Background is selected)

## When to use

- When you need to transition from legacy HEX values to the perceptually accurate LCH color space for CSS.
- When working with semi-transparent colors that require accurate alpha channel compositing.
- When you need to maintain consistent perceived brightness and saturation across different color palettes.

## How it works

- Paste your HEX color codes into the input area, supporting both 3-digit, 6-digit, and 8-digit (alpha) formats.
- Select your preferred output format, such as standard CSS syntax or raw numerical values.
- Choose how to handle alpha channels by compositing them against a specific background color or ignoring them entirely.
- Click convert to generate the LCH values instantly for your design or development workflow.

## Use cases

- Modernizing CSS stylesheets by replacing legacy HEX colors with LCH for better accessibility.
- Generating color variations that maintain consistent lightness and chroma levels.
- Preparing design system assets for cross-platform consistency in color perception.

## Frequently asked questions

### Why use LCH instead of HEX?

LCH is perceptually uniform, meaning it aligns better with how the human eye perceives color, making it easier to create accessible and balanced color palettes.

### Does this tool support transparency?

Yes, you can process HEX values with alpha channels and choose to composite them against a white, black, or custom background.

### Can I convert multiple colors at once?

Yes, simply paste each HEX code on a new line in the input area to batch convert your entire palette.

### What is the difference between the output formats?

The formats range from standard CSS-ready strings like 'lch(50 50 180)' to raw comma-separated values for use in programmatic applications.

### Is the conversion accurate?

The tool uses standard color space transformation algorithms to ensure high-precision conversion from sRGB (HEX) to CIELCH.
