## Overview

The Adobe RGB to LCH Converter allows you to precisely transform Adobe RGB color values into the perceptually uniform LCH (Luminance, Chroma, Hue) color space, facilitating more intuitive color adjustments and consistent design workflows.

## Inputs

- **Adobe RGB Input** (textarea): Enter Adobe RGB values, one per line: adobe-rgb(255,0,128) adobe-rgba(255,0,128,0.5) adobergb(255,0,128) adobergba(255,0,128,0.5) 255,0,128 255,0,128,0.5 R:255 G:0 B:128 R:255 G:0 B:128 A:0.5
- **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 perform perceptually accurate color manipulations that are difficult to achieve in RGB.
- When preparing assets for modern web standards that support CSS LCH color definitions.
- When you need to flatten transparent colors by compositing them against a specific background color before conversion.

## How it works

- Paste your Adobe RGB values into the input field using standard formats like rgb(r,g,b) or comma-separated values.
- Select your preferred output format, such as CSS-ready LCH syntax or labeled L, C, and H values.
- Choose how to handle alpha channels by compositing with a solid color or ignoring transparency.
- Click convert to generate the corresponding LCH color values instantly.

## Use cases

- Standardizing color palettes for cross-platform design systems.
- Converting legacy print-ready Adobe RGB colors for modern web development.
- Adjusting color lightness while maintaining consistent hue and chroma.

## Frequently asked questions

### Why convert Adobe RGB to LCH?

LCH is perceptually uniform, meaning it aligns better with how human eyes perceive color, making it easier to adjust lightness or saturation without shifting the hue.

### Does this tool support transparency?

Yes, you can choose to composite transparent colors against a white, black, or custom background color during the conversion.

### What input formats are accepted?

The tool accepts various formats including adobe-rgb(r,g,b), comma-separated values, and labeled R: G: B: inputs.

### Can I use the output directly in CSS?

Yes, by selecting the 'lch(L C H)' or 'lch(L C H / A)' output format, you get values ready for modern CSS stylesheets.

### What happens if I choose to ignore the alpha channel?

The tool will process the RGB values as fully opaque, discarding any transparency data provided in the input.
