Today, synthetic ultramarine is widely available, offering a more affordable alternative. This color is popular in design for its ability to evoke feelings of peace, trust, and authority.

The color #1B08AC, a deep ultramarine, presents several accessibility considerations. Its low luminance value means text rendered in this color requires careful pairing with a very light background to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using this color for text on a dark or moderately colored background would likely fail accessibility standards. In user interface design, avoid using #1B08AC as the sole indicator of interactive elements, as users with color vision deficiencies may not be able to distinguish them. Providing supplementary cues, such as labels or icons, is crucial. When using this color for decorative purposes, ensure it doesn't interfere with the user's ability to perceive and understand important content. A thorough accessibility audit using tools that simulate color blindness and calculate contrast ratios is recommended to ensure compliance with accessibility standards.
