The hex color #11188A, also known as Ultramarine, presents some accessibility challenges, especially regarding text contrast. When used as a background color, it is crucial to select a foreground color that provides sufficient contrast to ensure readability. White or very light shades of yellow or green are typically good choices, offering the necessary contrast ratio as defined by WCAG guidelines. Conversely, using darker colors or shades too similar to Ultramarine as foreground text should be avoided, as it can make the text difficult or impossible to read for users, particularly those with visual impairments. It's recommended to use contrast checking tools to verify that color combinations meet accessibility standards, ensuring a positive user experience for everyone. Remember to consider the size and weight of the text, as smaller or lighter fonts may require even greater contrast.
