Convert between color formats (HEX, RGB, HSL) and generate accessible color palettes with WCAG compliance checking and color blindness simulation.

Enter a color in any format to convert.

Processed locally

This color converter processes all color conversions, palette generation, contrast checking, and image analysis entirely on your device using your browser's processing power. No color data, palette information, or images are ever transmitted to any server. Your work remains completely private.

About this color converter

Converting colors between different formats is essential for designers, developers, and digital professionals. Whether you're working with HEX codes, RGB values, or HSL colors, the Color Converter & Palette Generator eliminates the need for multiple tools. Our free color converter instantly transforms colors between HEX, RGB, HSL, HSV, and CMYK formats, streamlining your workflow and ensuring consistency across all your design and development projects.

Beyond basic hex to RGB conversion, this comprehensive tool includes advanced features that set it apart from standard color converters. Generate harmonious color palettes automatically, check WCAG contrast ratios for accessibility compliance, and simulate how your designs appear to people with different types of color blindness. The integrated color blindness simulator lets you test your color schemes for deuteranopia, protanopia, and tritanopia, ensuring your designs work for everyone.

Real-world applications span across web design, brand development, UI/UX design, data visualization, and digital accessibility. Marketing teams use the color palette generator to create cohesive brand color schemes, developers rely on the WCAG contrast checker to meet accessibility standards, and designers leverage color blindness simulation to ensure inclusive, accessible designs. The tool also includes image color extraction for analyzing and matching colors from existing artwork.

All color conversions and analysis happen entirely in your browser with zero data transmission. Your colors, palettes, and images are processed locally on your device—nothing is uploaded to external servers. This ensures complete privacy while you work with sensitive brand colors or proprietary design schemes.

Whether you need a simple hex to RGB converter, a complete color palette generator, WCAG accessibility checking, or color blindness testing, this all-in-one color tool provides everything in one free, fast, and reliable interface.

How to use this tool

  1. 01

    Enter or Select Your Color

    Start by inputting your color in any supported format—paste a HEX code like #FF5733, enter RGB values (255, 87, 51), HSL notation, or use the color picker to select directly from your screen or any element.

  2. 02

    Convert to Your Desired Format

    Instantly see your color converted across all supported formats including HEX, RGB, HSL, HSV, CMYK, and color names. Copy any format with a single click for direct use in your code, design tools, or specifications.

  3. 03

    Generate Palettes & Verify Accessibility

    Create complementary, analogous, triadic, or custom color palettes in seconds. Use the WCAG contrast ratio checker to verify your color combinations meet AAA accessibility standards for both regular and large text.

  4. 04

    Test Color Blindness & Extract Colors

    Preview how your palette appears to users with color vision deficiency using the color blindness simulator. Upload images to automatically extract dominant colors and analyze them for contrast ratios and accessibility compliance.

Limits and edge cases

  • All color conversions and palette generation happen locally in your browser—nothing is transmitted to servers. Your colors, palettes, and images remain completely private and secure throughout your entire session.
  • WCAG contrast ratio standards require 4.5:1 for normal text (AA level) and 7:1 for AAA level. Large text needs only 3:1 (AA) or 4.5:1 (AAA). Use the contrast checker to ensure your color combinations meet these accessibility requirements.
  • The color blindness simulator uses scientifically-validated algorithms based on cone cell response models. While individual perception varies, this tool provides excellent practical guidance for testing design accessibility with deuteranopia, protanopia, and tritanopia color vision deficiencies.

Common questions

What color formats does this free converter support?

This color converter supports HEX, RGB, HSL, HSV, CMYK, and CSS color names. Enter your color in any format and instantly see it converted to all others. Copy any format directly to your clipboard for use in code, design tools, or specifications.

How accurate is the color blindness simulator?

The color blindness simulator uses scientifically-validated algorithms based on research into color vision deficiency. It accurately simulates deuteranopia, protanopia, and tritanopia. While individual color perception varies, this simulator provides excellent practical guidance for ensuring your designs are accessible to people with color blindness.

What WCAG contrast ratios should I aim for?

WCAG 2.1 guidelines require 4.5:1 contrast ratio for normal text (AA level) and 7:1 for AAA level compliance. For large text (18pt+ or 14pt+ bold), AA requires 3:1 contrast. Our WCAG contrast checker displays your ratio and indicates which accessibility standards your color combination meets.

Can I extract colors from images?

Yes! Upload any image to automatically extract the dominant colors and generate a color palette. The tool analyzes your image and provides HEX, RGB, and HSL values for each extracted color, plus WCAG contrast analysis.
