#0F0D8A

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0F0D8A, is a deep blue pigment derived from lapis lazuli. Historically, it was one of the most expensive and highly prized colors, often reserved for painting the robes of the Virgin Mary in religious art. The name "ultramarine" comes from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was imported to Europe from mines in Afghanistan. In modern times, synthetic ultramarine is widely available, offering the same vibrant hue at a fraction of the cost. It is known for its excellent lightfastness and stability, making it a reliable choice for artists and designers alike. This color evokes feelings of calm, trust, and authority.

The color #0f0d8a, a deep ultramarine, presents several accessibility considerations for web development. Its low luminance requires careful attention to contrast ratios. When used as text, it's crucial to pair it with a light background to ensure readability, adhering to WCAG guidelines for contrast. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. If used for interactive elements like buttons or links, sufficient contrast is essential for users with visual impairments to perceive the interactive affordance. Avoid using this color for crucial information without providing alternative cues, such as icons or text labels, for users who may have difficulty distinguishing it due to color vision deficiencies. Careful consideration of colorblindness simulations can further enhance the inclusive design.
