The color #1A09AB, also known as Ultramarine, presents accessibility challenges, particularly concerning color contrast. When used as a foreground color, it requires a very light background to meet WCAG (Web Content Accessibility Guidelines) standards for normal text (AA) and enhanced contrast for larger text (AAA). Using it as a background necessitates a very light foreground color. Ensuring sufficient contrast is vital for users with visual impairments. Tools like contrast checkers can accurately assess the contrast ratio, which should be at least 4.5:1 for normal text and 3:1 for large text. Therefore, careful consideration and testing are essential to maintain accessibility. It's also important to consider users with color vision deficiencies. Avoid using #1A09AB as the sole indicator of critical information.
