The color #090D8F, a deep ultramarine, presents significant accessibility challenges. Its low luminance of 3.82 cd/m² results in poor contrast against standard white backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color falls far short, making text difficult to read for users with visual impairments. To improve accessibility, consider pairing it with much lighter shades. White, light yellows, or light blues would offer better contrast. Implementing text shadows or using a thicker font weight might offer minor improvements but are unlikely to meet accessibility standards alone. A thorough assessment using accessibility tools is crucial to ensure readability and inclusivity for all users. Also, avoid using it for crucial interactive elements without proper contrast.
