Ultramarine

#010F97

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #010F97, is a deep blue pigment with a rich history and widespread use. Derived from the Latin 'ultramarinus,' meaning 'beyond the sea,' it was originally made from the precious gemstone lapis lazuli, sourced from Afghanistan. Historically, Ultramarine was highly valued, often more expensive than gold, and reserved for use in important religious paintings, particularly for depicting the robes of the Virgin Mary. Today, synthetic Ultramarine is readily available, offering the same vibrant hue at a more affordable cost. This color is characterized by its intense, non-subtle, and slightly reddish-blue tone. Ultramarine symbolizes wisdom, devotion, and stability and is frequently used to invoke feelings of trust and authority.

The color #010F97, Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue results in very low contrast against lighter backgrounds, potentially making text or interactive elements difficult to read. According to WCAG guidelines, sufficient contrast ratios are crucial for readability. To ensure accessibility, Ultramarine should ideally be paired with very light colors, such as white or pale yellow, to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Careful consideration is needed when using this color for essential UI components like buttons or links. Providing alternative text descriptions for images using this color is also essential to ensure screen reader compatibility. Furthermore, avoid using Ultramarine as the sole indicator for important information; supplement it with labels, icons, or other visual cues to accommodate users with color blindness.
