The color #11198A, a deep ultramarine, presents some accessibility challenges, particularly when used as a background or text color. Due to its low luminance, it requires careful consideration of color contrast ratios. When using this color for text, it is crucial to pair it with a light color to ensure readability for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as per WCAG guidelines. Using color contrast tools can help determine if the chosen color combination meets accessibility standards. Avoid using #11198A for crucial interactive elements without sufficient contrast as this makes it difficult to be seen. Testing with users is crucial to confirm the accessibility of color choices, especially for those with color vision deficiencies. The color should be carefully used with graphical elements as well.
