#110088

General Information about Ultramarine

The color #110088, commonly known as Ultramarine, is a deep shade of blue with a rich history. The term "ultramarine" originates from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally derived from lapis lazuli imported from Afghanistan by sea during the Middle Ages. Lapis lazuli was ground into a powder and processed to extract the pigment. Due to its laborious extraction process and the scarcity of lapis lazuli, ultramarine was historically one of the most expensive and highly prized pigments, often reserved for painting the robes of the Virgin Mary and other important figures in religious art. Nowadays, synthetic ultramarine is widely available and more affordable, but it retains its association with depth, sophistication, and royalty.

The color #110088, a deep ultramarine, presents several accessibility considerations for web design. Due to its low lightness value, it has inherently low contrast against common background colors like white. This poses a significant challenge for users with visual impairments, who may struggle to distinguish text or elements rendered in this color. To ensure accessibility, it's crucial to pair #110088 with very light foreground colors such as white or bright yellow to meet WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. Tools like contrast checkers can help verify compliance. Avoid using this color for essential interactive elements or small text without careful consideration of its contrast. Furthermore, provide alternative visual cues for users who may have difficulty perceiving color differences. Using it with other blues might create problems for people with Tritanopia.
