The color #100497, a deep shade of ultramarine, presents several accessibility considerations for web developers. Its dark nature means it generally requires light-colored text for sufficient contrast. Using a color contrast checker is crucial to ensure compliance with WCAG guidelines, specifically a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. When used for interactive elements like buttons or links, hover and focus states should be clearly indicated with contrasting colors or visual cues to assist users with visual impairments or those relying on keyboard navigation. Avoid using this color as the sole indicator of important information, as users with color blindness may not be able to differentiate it effectively. Employing supplementary cues like text labels or icons can improve overall usability. Thorough testing with assistive technologies is recommended to guarantee the color scheme is accessible to all users.
