About Ultramarine (#1E10A4)

Ultramarine, represented by the hexadecimal color code #1E10A4, is a deep and intense shade of blue. It derives its name from the Latin 'ultramarinus', meaning 'beyond the sea,' as it was originally imported from mines in Afghanistan by sea. Historically, it was a highly prized pigment made from ground lapis lazuli, making it extremely expensive and reserved for important works of art. In modern times, synthetic ultramarine is readily available, making it a widely used color in various applications. Its unique spectral reflectance contributes to its rich appearance, setting it apart from other blue hues. It is often associated with royalty, intelligence, and spirituality.

The color #1E10A4, a deep ultramarine, presents several accessibility considerations for web development. Its dark hue results in a low luminance value, meaning it requires careful attention to color contrast. When used as a foreground color, it's crucial to pair it with a light background to ensure sufficient contrast for readability, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, according to WCAG guidelines. Insufficient contrast can make it difficult for users to distinguish text from the background, leading to a poor user experience. Furthermore, avoid using this color alone to convey important information, as users with color blindness may not be able to perceive it effectively. Supplement color cues with text labels or icons to ensure inclusivity.
