#150EA5

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #150EA5, is a deep blue pigment originally derived from the precious stone lapis lazuli. The name "ultramarine" comes from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was imported to Europe from mines in Asia. Historically, it was highly prized for its brilliance and color stability, often used in Renaissance paintings for depicting the robes of the Virgin Mary. Today, synthetic ultramarine is widely available, offering the same vibrant hue at a lower cost. It is now used in various applications, including paints, plastics, cosmetics, and textiles. The color is associated with depth, clarity, and richness.

The hex color #150EA5, also known as Ultramarine, presents some accessibility challenges, primarily due to its dark hue. When used as a background color, sufficient contrast with foreground text is essential to ensure readability 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. Using a light color such as white or a very pale yellow as the foreground color can help meet these contrast requirements. It's important to test color combinations using accessibility tools to verify compliance. When used for interactive elements, such as buttons or links, consider providing additional visual cues, like underlines or borders, to enhance usability for users who may not be able to distinguish color effectively. Always consider the needs of all users by testing and evaluating your color choices.
