#1B12A2

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1B12A2, is a deep blue color with a rich history. It is derived from the pigment made from ground lapis lazuli, a semi-precious stone, making it historically one of the most expensive and highly prized pigments. The name "ultramarine" comes from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was imported to Europe from mines in Afghanistan. In color theory, Ultramarine evokes feelings of tranquility, depth, and sophistication. It is often associated with royalty, wisdom, and spirituality. In modern usage, it remains a popular color in art, design, and fashion, valued for its intense and captivating hue.

The color #1B12A2, also known as Ultramarine, presents some accessibility challenges, especially when used as a background or text color. Its dark hue provides insufficient contrast with lighter text colors, potentially making it difficult for users with visual impairments to read content. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #1B12A2 with white text may not meet these standards, requiring careful consideration and testing with accessibility evaluation tools. For optimal readability, it's advisable to pair it with much lighter colors or to use it sparingly for decorative elements where legibility is not paramount. Providing alternative high-contrast themes can greatly enhance the user experience for individuals with visual sensitivities.
