The name 'Ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the original pigment was derived from lapis lazuli imported from distant lands.

The color #180893, a deep shade of ultramarine, presents significant accessibility challenges, especially in web design. Its very low luminance of approximately 2% necessitates careful consideration of color contrast. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments. To ensure readability, text using #180893 as a background must be paired with a very light text color, ideally white or a near-white shade. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Avoid using #180893 for interactive elements like buttons or links without providing clear visual cues, such as borders or icons, to differentiate them from the background. It's also advisable to test the color combination with accessibility tools to confirm compliance and ensure a positive user experience for everyone.
