#1506AE

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1506AE, is a deep blue pigment historically derived from the precious stone lapis lazuli. The name 'ultramarine' literally means 'beyond the sea,' reflecting its origin as a pigment imported to Europe from mines in Asia. Chemically, it is a complex sodium aluminum silicate with sulfur, giving it its characteristic blue color. This color is highly valued for its brilliance and lightfastness, making it a popular choice among artists for centuries. In modern applications, ultramarine is used in a variety of products, including paints, cosmetics, and plastics. It is also used in laundry detergents as a bluing agent to counteract yellowing and brighten white fabrics.

The color #1506AE, Ultramarine, presents significant accessibility challenges due to its dark hue. When used as a background, it requires very light text (ideally white or a very pale yellow) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using darker shades of text on this background will likely fail accessibility tests, making content difficult to perceive for users with visual impairments. When using it for interactive elements, consider adding visual cues beyond color alone, such as underlines for links or icons for buttons, to ensure usability for all users, including those with color blindness. Proper testing with accessibility tools is crucial to ensure compliance and an inclusive user experience. Consider providing alternative color schemes for users who prefer different contrast levels.
