## Overview

The Grayscale Converter is a professional design utility that allows you to transform any color into its monochrome equivalent using precise mathematical algorithms and adjustable intensity settings.

## Inputs

- **Base Color** (color): #FF5733
- **Conversion Method** (select)
- **Grayscale Intensity (%)** (range)
- **Single Channel Selection** (select)
- **Custom RGB Weights** (textarea): Enter custom weights as JSON format. Example: {"red": 30, "green": 59, "blue": 11}
- **Preserve Original Luminance** (checkbox)
- **Batch Colors (Optional)** (text): Enter multiple colors separated by commas (e.g., #FF0000, #00FF00, #0000FF)
- **Include Original Colors** (checkbox)
- **Show Side-by-Side Comparison** (checkbox)

## When to use

- Testing UI accessibility and contrast ratios for color-blind users.
- Creating consistent monochrome color palettes for minimalist design projects.
- Analyzing the luminance values of specific brand colors or design elements.

## How it works

- Input your base color or a list of batch colors to be processed.
- Select a conversion method such as Luminosity, Average, or Desaturation to define how the gray value is calculated.
- Adjust the intensity slider to control the depth of the grayscale effect.
- Enable side-by-side comparison to view the original and converted colors simultaneously.

## Use cases

- Validating UI component visibility in grayscale mode.
- Generating a monochromatic color scheme from a primary brand color.
- Extracting specific channel data (Red, Green, or Blue) for image processing tasks.

## Frequently asked questions

### What is the difference between Luminosity and Average methods?

The Luminosity method uses weighted RGB values to match human perception, while the Average method treats all channels equally.

### Can I process multiple colors at once?

Yes, use the Batch Colors field to input a comma-separated list of hex codes for simultaneous conversion.

### How do custom weights work?

You can provide a JSON object defining specific R, G, and B percentage weights to create a custom grayscale formula.

### Does this tool support transparency?

The tool focuses on color conversion; it processes the RGB components of your input colors.

### Can I see the original color next to the result?

Yes, enable the 'Show Side-by-Side Comparison' option to display the original and converted colors together.

Paste a theme object (the kind registered via echarts.init(dom, themeName)) and the tool walks every leaf, tagging each color (with optional named/rgb → hex normalization), spacing number, font size and string, then emits clean CSS variables, a Tailwind theme.extend config, Style Dictionary tokens.json, or SCSS variables. Bridges the gap between an ECharts visualization theme and Figma/CSS/Tailwind design tokens without copying each value by hand.
