Kontrast is a free browser extension available on Chrome that allows users to quickly check and adjust text and background contrast in real-time. Its main purpose is to help websites meet the standards of Web Content Accessibility Guidelines (WCAG) requirements.

With Kontrast, users can easily inspect the contrast of the selected element and view the accessibility ratio. The extension also automatically suggests the closest WCAG-compliant color, making it easier to achieve the desired contrast. Additionally, Kontrast offers a color slider, allowing users to adjust colors in RGB and HSL modes.

The extension includes a color picker and provides the ability to copy colors in various formats such as HEX, RGBA, and HSLA. It also offers the option to ignore CSS hover effects, ensuring accurate contrast analysis. Lastly, Kontrast supports Dark Mode, providing a visually comfortable experience for users.

Kontrast has received recognition from Gary Simon of Coursetro.com, further validating its usefulness and quality.
