Outils de contrôle de contraste
A modern tool for exploring and finding accessible colors. Make sure that everyone can see your creations.
In the international reglementation etablished by the WCAG , the success criteria 1.4.3 requires a minimum contrast ratio of 4.5:1 (and 3:1 for enlarged text).
Contrast is the difference in luminance or color that makes an object (or its representation in an image or display) distinguishable. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view.
