General Information About Ultramarine

Ultramarine, represented by the hexadecimal color code #1D0C8F, is a deep blue pigment originally derived from the mineral lapis lazuli. Its name comes from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was imported to Europe from mines in Asia. Throughout history, ultramarine has been highly valued for its vibrant color and was often more expensive than gold. In art, it has been used extensively by renowned painters, including those of the Renaissance period, to depict the robes of the Virgin Mary and other significant figures. Today, synthetic ultramarine is widely available, offering the same beautiful hue at a more accessible cost. It remains a popular choice in various applications, from paints and inks to plastics and cosmetics, due to its stable and intense blue color.

The hex color #1D0C8F, a deep ultramarine, presents several accessibility considerations for web developers. Its high darkness value implies a need for light-colored text to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using a tool to evaluate the contrast ratio between #1D0C8F and the chosen text color is essential. Given its intensity, using this color for large blocks of text can strain the eyes, so it's best reserved for headings, accents, or interactive elements. Consider users with visual impairments who may struggle to distinguish between subtle shades; high contrast is key. Additionally, avoid using this color as the sole indicator of functionality, such as links, and always provide alternative cues like underlines or icons.
