• HEX

  HEX (Hexadecimal) is the most common color format used on the web. It represents colors using six hexadecimal digits that define the red, green, and blue components.

  Example:

  #3B82F6

  HEX is widely used in HTML, CSS, design tools, and branding guidelines.

• RGB

  RGB stands for Red, Green, Blue. Each color channel ranges from 0 to 255, allowing over 16 million possible color combinations.

  Example:

  rgb(59, 130, 246)

  RGB is commonly used for CSS, Canvas, SVG, and digital displays.

• HSL

  HSL stands for Hue, Saturation, and Lightness. It provides a more intuitive way to modify colors compared to RGB because you can independently adjust hue, saturation, and brightness.

  Example:

  hsl(217, 91%, 60%)

  HSL is popular for creating themes, hover effects, and dark/light mode color variations.

• OKLCH

  OKLCH is a modern perceptual color space that represents colors using L (Lightness), C (Chroma / color intensity), and H (Hue).

  Example:

  oklch(0.65 0.17 255)

  Unlike older color models, OKLCH is designed so equal numerical adjustments produce visually consistent changes, making it especially useful for accessible color palettes, design systems, and modern CSS workflows.

• Enter a color in any supported format.
• The tool automatically detects the format.
• All supported color formats update instantly.
• Copy any converted value with one click.
• Use the converted color in your CSS, design tool, or application.

No downloads or registration are required.

Different tools and frameworks use different color formats. A designer might export a HEX value from Figma, while a developer needs RGB or HSL for CSS. Modern CSS also supports OKLCH, making it easier to build visually balanced themes and accessible interfaces.

A Color Converter eliminates manual calculations, reduces errors, and ensures color consistency across design and development workflows.

OKLCH is becoming increasingly popular because it is based on human perception of color rather than raw RGB values.

Advantages include:

• More consistent lightness adjustments
• Better color interpolation
• Easier creation of accessible palettes
• More predictable gradients
• Improved dark mode design
• Better support for modern design systems

Many modern CSS frameworks and design tools are adopting OKLCH because it produces more visually uniform results than older color spaces.

• HEX, RGB, and HSL are supported by all modern browsers.
• OKLCH is supported in current versions of Chrome, Edge, Firefox, and Safari, making it suitable for modern web applications. If compatibility with older browsers is required, you can convert OKLCH colors to HEX or RGB before deployment.

Choosing the right color format can simplify accessible design.

• Use HSL or OKLCH to adjust lightness while preserving hue.
• Test text and background contrast before publishing.
• Maintain sufficient contrast for readability.
• Build consistent light and dark themes using perceptually uniform colors.
