About The Color Converter & Contrast Checker

Designers and developers constantly need to translate colors across different formats. A designer might provide a HEX code (#FF5733), but a developer might need the RGB format for opacity adjustments, or the HSL format for programmatic theme generation.

This utility instantly converts any valid color input into HEX, RGB, and HSL formats simultaneously. Furthermore, it acts as a critical Web Accessibility (WCAG) compliance tool. By selecting a text color and a background color, it mathematically calculates the contrast ratio, instantly telling you if your design is readable and accessible to visually impaired users.

How to Use

  1. Enter a color in HEX, RGB, or HSL format into the primary input box.
  2. The tool will instantly calculate and display the corresponding values for all other color formats.
  3. To check accessibility, scroll down to the Contrast Checker.
  4. Input a text color and a background color to instantly see if they pass WCAG AA and AAA accessibility standards.

Frequently Asked Questions

What is the difference between RGB and HSL?

RGB defines a color by mixing Red, Green, and Blue light. HSL defines a color by its Hue (position on the color wheel), Saturation, and Lightness, making it much easier for developers to programmatically create lighter/darker shades.

What is WCAG Contrast Accessibility?

The Web Content Accessibility Guidelines (WCAG) require that text has a high enough mathematical contrast ratio against its background so that visually impaired or colorblind users can read it easily.

What is the passing ratio for WCAG AA?

For normal text, the WCAG AA standard requires a contrast ratio of at least 4.5:1. For large text (headings), the requirement is slightly lower at 3.0:1.
