This color is often associated with concepts like trustworthiness, stability, and intelligence. Ultramarine has a rich history, originally derived from the rare and expensive mineral lapis lazuli.

This color evokes a sense of depth and sophistication and continues to be popular in design and branding.

The hex color #1B0EA6, Ultramarine, presents some accessibility challenges, particularly regarding color contrast. When used as a background color, it necessitates light-colored text to ensure readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to meet WCAG (Web Content Accessibility Guidelines) standards. Tools like contrast checkers can help verify compliance. Due to its deep hue, #1B0EA6 is not ideal for conveying critical information alone, such as in error messages, without supplementary cues like icons or text labels. Sufficient spacing between elements and clear typography contribute to improved usability. When using this color for interactive elements like buttons, ensure sufficient contrast for different states (hover, focus, active) to provide clear visual feedback to users.
