The color #100DA7, Ultramarine, presents potential accessibility challenges, particularly concerning color contrast. When used as text against a white background, the contrast ratio may fall below the WCAG (Web Content Accessibility Guidelines) recommended levels for readability, especially for users with visual impairments. To ensure accessibility, it is advisable to pair Ultramarine with lighter background colors like whites, creams, or very light yellows. Similarly, when used as a background color, pairing it with white or very light-colored text would enhance readability. Consider using contrast checker tools to verify compliance with accessibility standards. Additionally, avoid relying solely on color to convey important information; supplement it with text labels or icons to cater to users with color vision deficiencies. Ensuring sufficient contrast enhances the overall user experience and makes the content accessible to a wider audience.
