It derives its name from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally made from lapis lazuli imported from Asia. Historically, it was a highly prized pigment used in paintings, often associated with royalty and religious figures due to its rarity and expense. In the RGB color model, Ultramarine consists of 11.4% red, 7.8% green, and 62.4% blue. Its CMYK values are 82% cyan, 88% magenta, 0% yellow, and 38% black.

Understanding its composition and historical context provides valuable insight into its usage and appeal.

The color #1D149F, also known as Ultramarine, presents significant accessibility challenges, particularly concerning color contrast. When used as a background color, it necessitates very light 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) AA standards. Using a color contrast checker is crucial to verify compliance. Avoid pairing Ultramarine with mid-tone colors as the contrast will likely be insufficient for users with visual impairments. Consider providing alternative color schemes that offer higher contrast options for users with low vision or color blindness. Furthermore, rely not only on color to convey important information; supplement it with text labels or icons. Ensure that interactive elements, such as links and buttons, have a distinct visual focus indicator when selected, as mandated by accessibility standards. Thoughtful design choices can significantly enhance the inclusivity of digital content featuring Ultramarine.
