Its deep hue makes it suitable for creating a sense of depth and mystery in designs.

The hex color #1B10A4, also known as Ultramarine, presents several accessibility considerations for web development. Its dark hue results in a low luminance value, which means it requires careful pairing with text and other user interface elements. According to WCAG guidelines, sufficient contrast is essential for readability and usability, particularly for users with visual impairments. A large text should have a contrast ratio of at least 3:1, while small text should have a contrast ratio of at least 4.5:1 against its background. When using #1B10A4 as a background color, ensure that the foreground text is a light color such as white or a light shade of yellow to meet these contrast requirements. Tools like WebAIM's contrast checker can assist in verifying compliance. It's also important to avoid using color as the sole means of conveying information, as this can exclude users who are colorblind. Providing alternative cues, such as text labels or icons, can enhance accessibility. Additionally, consider that users may override website styles to suit their individual needs, so designing with flexibility in mind is crucial for inclusivity.
