#1D0EA6

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1D0EA6, is a deep blue color with a rich history. The term 'ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally imported from Afghanistan. Historically, it was derived from the gemstone lapis lazuli, making it a highly prized and expensive pigment, often reserved for important works of art, especially depictions of the Virgin Mary in religious paintings. Today, synthetic versions of ultramarine are widely available, making it more accessible for various applications. Ultramarine blue is known for its exceptional lightfastness and vibrant hue, making it a popular choice in art, design, and various industries.

The color #1D0EA6, also known as Ultramarine, presents significant accessibility challenges, especially in web design. Its dark hue results in low contrast against lighter backgrounds, making text and interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Ultramarine often falls short of these recommendations when paired with common background colors like white or light gray. To improve accessibility, consider using Ultramarine sparingly and ensure it is always paired with a very light color (or white) to achieve sufficient contrast. Alternatively, using a lighter tint or shade of Ultramarine can also help improve readability and overall accessibility for a wider audience.
