Information on the Contrast Checker “Contrastive”

What is color contrast?

Color contrast describes the difference in brightness between two colors that appear next to each other in the layout. It plays a central role in visual design, as it improves legibility and ensures that content can also be clearly perceived by people with visual impairments. Good contrast is not only aesthetically important, but also crucial for accessible and inclusive design.

Why is color contrast important?

A high contrast between text and background makes reading easier – especially in different lighting conditions or on different devices. For people with visual impairments such as color vision deficiency or low vision, sufficient contrast is essential to be able to recognize text and interactive elements. Adhering to recommended contrast ratios helps to meet accessibility standards and make content accessible to a wider audience.

Why did we develop this tool?

Because even we experience time and again how quickly color contrast is overlooked – even in professional projects. Yet it is crucial for good legibility and accessibility.

We wanted a tool that shows quickly, clearly and easily whether two colors harmonize and meet the accessibility requirements. No frills, but with a focus on the essentials.
