General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1210A4, is a deep blue pigment originally derived from the precious mineral 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. Chemically, modern ultramarine is a complex sodium aluminosilicate containing sulfur. It's prized for its intense color and resistance to fading. In color theory, ultramarine is considered a cool color, often associated with tranquility, depth, and stability. It has been historically used in fine art, particularly in Renaissance paintings, and continues to be used in various applications, including paints, cosmetics, and plastics. Its rich hue and historical significance make it a popular and recognizable color across various industries.

The color #1210A4, also known as Ultramarine, presents several accessibility considerations for web developers. Given its dark hue, it is crucial to ensure sufficient contrast when used as a background or text color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular) against its background. Using lighter colors like white or bright yellow as foreground text would improve readability. Additionally, providing alternative visual cues, such as underlines or icons, can benefit users with color vision deficiencies. Avoid relying solely on color to convey important information; instead, incorporate text labels or patterns to ensure inclusivity and accessibility for all users. Testing the color combination with accessibility tools and getting feedback from users are vital steps in ensuring an accessible design. Screen readers rely on semantic HTML, so proper markup is crucial; assistive technologies can interpret the color and contrast differences to effectively communicate with users.
