#18149F

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #18149F, is a deep, rich blue pigment originally derived from the mineral lapis lazuli. The name 'ultramarine' comes from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was imported to Europe from mines in Asia. Historically, it was one of the most expensive and highly prized pigments, often reserved for painting the robes of the Virgin Mary in religious art. Today, synthetic ultramarine is widely available, offering the same vibrant color at a much lower cost. In the RGB color model, #18149F is composed of 9.41% red, 7.84% green, and 62.35% blue. It is a saturated color that evokes feelings of depth, stability, and sophistication.

The color #18149F, a deep ultramarine, presents accessibility challenges, particularly regarding color contrast. When used as a background, it necessitates very light text (white or near-white) to ensure sufficient contrast for readability, ideally meeting WCAG AA or AAA standards. Tools like contrast checkers can verify compliance. When used for text itself, a very dark background is required. Also consider that individuals with visual impairments, such as color blindness, might perceive this color differently, impacting their ability to distinguish elements. Therefore, avoid relying solely on this color to convey crucial information; supplement it with text labels or icons. Semantic HTML and ARIA attributes are essential for screen reader users. Ensure interactive elements have proper focus indicators that are clearly visible against this dark shade. Thorough testing with assistive technologies is crucial for ensuring inclusive design.
