General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1B0497, is a deep, vivid blue color with a hint of purple. Historically, Ultramarine was derived from the precious stone lapis lazuli, making it one of the most expensive and highly prized pigments during the Middle Ages and Renaissance. Its name literally means "beyond the sea," referring to its origin from overseas. Today, synthetic versions are widely available, making it more accessible for various applications. In color psychology, Ultramarine is associated with intelligence, trust, loyalty, and confidence. It's often used in branding and design to convey a sense of authority and stability. The color is visually striking and can evoke feelings of calmness and serenity, but it's also perceived as serious and formal. Its spectral reflectance is centered around the blue wavelengths, contributing to its characteristic deep hue.

The hex color #1B0497, also known as Ultramarine, presents significant accessibility challenges, particularly concerning color contrast. When used as a background color, text needs to be very light (ideally white or near-white) to achieve sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards. Using darker text colors against this background will likely result in very poor readability, making the content inaccessible to users with visual impairments. Similarly, if #1B0497 is used as a text color, the background needs to be a very light color. Ensure that the contrast ratio is at least 4.5:1 for normal text and 3:1 for large text to comply with accessibility standards. Careful consideration should also be given to users with color vision deficiencies, as the perception of this color can vary. It's crucial to test the color combination using accessibility tools to ensure it meets the necessary contrast requirements for a wide range of users.
