Ensure that your design is understandable and accessible to all. Validate the contrast between your text and graphic elements according to the WCAG 2.1 standards, simulate visual impairments, explore optimal color combinations for maximum readability, and easily convert these colors to hex, hex/a, rgba, hsla, hwb, or even CMYK (in experimental mode).
Subscribe and discover how Colors Tester can simplify your accessibility verification process, enabling you to create inclusive and impactful designs.
