When used as a foreground color for text, it requires careful pairing with a background color that offers sufficient contrast to ensure readability for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Therefore, it's advisable to use lighter colors such as whites, yellows, or light grays as backgrounds. Additionally, relying solely on color to convey important information should be avoided. Supplementing color with textual cues or icons can make the content more accessible to users who are colorblind or have other visual disabilities. Testing the color combination with accessibility tools is crucial to guarantee compliance with accessibility standards and provide an inclusive user experience.
