About Ultramarine

Ultramarine, represented by the hex code #1808AC, is a deep blue color with a rich history rooted in the pigment derived from the mineral lapis lazuli. Historically, it was one of the most expensive and prized pigments, used by Renaissance painters to depict scenes of great importance and luxury, most notably in depictions of the Virgin Mary's robes. Chemically, it is a complex sodium aluminosilicate with trace amounts of sulfur. In the digital world, #1808AC displays a particular shade of blue with distinct RGB values. This vibrant, slightly violet-tinged blue conveys a sense of depth, mystery, and sophistication. Its digital representation maintains the historical significance and visual impact associated with this color.

The hex code #1808AC, also known as Ultramarine, presents significant accessibility challenges, especially 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 comply with WCAG guidelines. Using a color contrast checker is crucial to verify compliance. Consider avoiding this color for critical UI elements or interactive components if sufficient contrast cannot be achieved. For individuals with visual impairments, insufficient contrast can render content illegible, hindering their ability to navigate and interact with the web page. Therefore, careful consideration and testing are essential when incorporating #1808AC in design.
