The digital representation allows for consistent and precise color reproduction across various media.

In the world of color theory, Ultramarine is often associated with concepts like depth, stability, and trust.

The color #111787, also known as Ultramarine, presents significant accessibility challenges, particularly in text-based applications. Its dark hue results in low contrast against typical light backgrounds, potentially making it difficult for users with visual impairments to read. To ensure readability, it's crucial to pair this color with a very light foreground color, such as white or a pale yellow. A contrast ratio of at least 4.5:1 is recommended for body text, as per WCAG guidelines. Larger text can tolerate a slightly lower contrast ratio of 3:1. Avoid using this color for crucial interactive elements without careful consideration of contrast. When used in graphical elements, ensure that sufficient color difference exists between adjacent elements to facilitate distinguishability for users with color vision deficiencies. Providing alternative high-contrast themes can significantly improve the overall user experience.
