General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #210497, is a deep, vivid blue pigment originally derived from the mineral lapis lazuli. Highly prized for its intense color, Ultramarine was historically more expensive than gold and reserved for use in important works of art, particularly during the Renaissance period. Today, synthetic versions of Ultramarine are widely available, making it an accessible and versatile color in various applications. The color is created by mixing sodium aluminum silicate with sulfur, resulting in its distinctive hue. In the RGB color model, #210497 is composed of 12.94% red, 1.57% green, and 59.22% blue. It is associated with feelings of royalty, wisdom, and tranquility. Ultramarine continues to be used extensively in paints, cosmetics, and other industries where a rich, stable blue color is required.

The color #210497, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue results in low contrast against lighter backgrounds, potentially making text and interactive elements difficult to read. According to WCAG guidelines, sufficient contrast is crucial for readability. To improve accessibility, consider pairing Ultramarine with very light colors like #FFFFFF or #F0F0F0 to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Additionally, avoid using Ultramarine as the sole indicator for interactive elements; supplement it with clear labels or icons. Providing alternative high-contrast themes enhances the user experience for individuals with varying visual needs, adhering to inclusive design principles. Testing with accessibility tools can further validate color choices and identify potential issues.
