The color #210CA8, also known as Ultramarine, presents significant accessibility challenges, particularly concerning color contrast. When used as text against a white background, it fails to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio, making it difficult for users with visual impairments to read. To improve accessibility, consider pairing it with lighter shades of yellow or white for text. When using it for interactive elements, ensure sufficient contrast to clearly indicate the interactive area. Providing alternative visual cues such as icons or labels alongside the color can also enhance usability for users who have difficulty distinguishing the color itself. Additionally, avoid using this color as the sole indicator of important information, such as error messages, as this excludes users with color blindness. Thoroughly testing with accessibility tools is crucial to identify and address potential issues.
