Ultramarine

#1905AE

General Information

Ultramarine, represented by the hex code #1905AE, is a deep blue pigment historically derived from the gemstone lapis lazuli. The name "ultramarine" comes from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was imported into Europe from Asia. Known for its rich, intense hue and excellent lightfastness, ultramarine has been prized by artists since the Middle Ages. In modern times, synthetic ultramarine is widely available, offering the same vibrant color at a more affordable price. This color evokes feelings of depth, stability, and sophistication. Ultramarine remains a popular choice in various applications, including fine art, graphic design, and decorative arts, valued for its timeless beauty and versatility.

The color #1905AE, Ultramarine, presents accessibility challenges, especially when used as text or interactive elements. Its dark hue requires careful consideration of contrast ratios against background colors. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using Ultramarine, light colors like white, yellow, or light green are preferable for the background to ensure readability. Using color alone to convey information should be avoided; supplemental cues like text labels or icons are essential. Proper color contrast testing tools can help developers verify compliance and enhance the user experience for everyone, including those with color vision deficiencies.
