The hex color #1B07AC, also known as Ultramarine, presents significant accessibility challenges, especially in web design. Its dark hue necessitates very light text colors for adequate contrast. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to perceive content effectively. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using white text (e.g., #FFFFFF) on an Ultramarine background may approach acceptable contrast, but careful testing with accessibility tools is essential. Avoid pairing this color with other dark shades, as it will render text illegible for many users. Consider using Ultramarine sparingly, primarily for decorative elements or backgrounds where text is minimal. When using it, ensure that interactive elements like buttons and links have clear visual cues beyond color alone, such as underlines or icons, to aid users who may have difficulty distinguishing between colors. Adequate spacing and sizing of elements are also important to improve readability and usability for all users.
