## Overview

The sRGB to LAB Converter allows you to precisely transform sRGB color values into the CIELAB color space, ensuring accurate color management and device-independent color representation.

## Inputs

- **sRGB Input** (textarea): Enter sRGB values, one per line: srgb(255,0,128) srgba(255,0,128,0.5) rgb(255,0,128) rgba(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 #FF0080 #FF008080 ff0080 ff008080
- **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 preparing assets for professional print workflows that require device-independent color profiles.
- When you need to perform color calculations or comparisons that are more perceptually uniform than sRGB.
- When converting web-based colors that include transparency (alpha channels) into a standardized LAB format.

## How it works

- Input your sRGB values using various formats like hex codes, RGB triplets, or CSS-style strings.
- Select your preferred output format, such as standard lab() syntax or simple comma-separated values.
- Choose how to handle transparency by compositing the alpha channel against a white, black, or custom background color.
- Click convert to generate the corresponding LAB color coordinates instantly.

## Use cases

- Standardizing brand colors across digital and print media by converting web hex codes to LAB.
- Calculating color differences (Delta E) by converting sRGB values into the perceptually uniform LAB space.
- Processing UI design assets with transparency for integration into color-managed software.

## Frequently asked questions

### What is the difference between sRGB and LAB?

sRGB is a device-dependent color space optimized for screens, while LAB is a device-independent color space designed to represent all colors visible to the human eye.

### How does the tool handle alpha channels?

The tool composites the transparent color over a selected background color (white, black, or custom) before performing the conversion to ensure a solid color result.

### Can I convert multiple colors at once?

Yes, you can paste multiple sRGB values into the input area, each on a new line, to convert them in a single batch.

### Which output format should I choose?

Choose 'lab()' for CSS compatibility, 'simple' for data processing, or 'labeled' for human-readable documentation.

### Is the conversion accurate for print?

LAB is the standard for color communication in print, making this tool ideal for bridging the gap between digital design and physical production.
