Ultramarine derives its name from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally imported from mines in Afghanistan. Historically, it was made by grinding lapis lazuli into a powder.

Today, synthetic ultramarine is readily available, making it a widely accessible color for various applications.

The color #0B08AC, a deep ultramarine, presents significant accessibility challenges, particularly in web design. Its low luminance value necessitates careful consideration of contrast ratios. According to WCAG guidelines, sufficient contrast between text and background is crucial for readability, especially for users with visual impairments. When using #0B08AC as a background, ensure that text is a light color, such as white or a very pale yellow, to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Avoid pairing it with other dark colors, as this will render content inaccessible. Furthermore, provide alternative cues beyond color alone to convey information. For example, use icons or text labels in addition to color to distinguish between different states or categories. Remember to test your designs with accessibility tools and real users to ensure they meet the needs of everyone.
