General Information about Ultramarine

Ultramarine, represented by the hex code #040F97, is a deep blue color with a rich history. Originally derived from the gemstone lapis lazuli, ultramarine was highly valued and expensive, often reserved for depicting religious figures in paintings. The name "ultramarine" comes from the Latin "ultramarinus," meaning "beyond the sea," reflecting the fact that the pigment was imported to Europe from overseas. In modern color theory, ultramarine is considered a cool color, associated with calmness, trust, and stability. It is frequently used in branding and design to convey professionalism and reliability. Its deep hue makes it versatile for both digital and physical applications, although considerations for accessibility are important due to its low lightness value.

The color #040F97, a deep ultramarine, presents some accessibility challenges, especially concerning color contrast. When used as a background, it necessitates very light text (white or near-white) to ensure readability and compliance with WCAG guidelines. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Using this color for interactive elements requires careful consideration, as users with visual impairments might struggle to identify clickable areas. Text links should be underlined or otherwise visually distinguished, and form fields should have clear, high-contrast borders. It's crucial to test color combinations with accessibility tools to guarantee usability for all users, including those with color blindness or low vision. Additionally, avoid using color alone to convey critical information; always provide redundant cues like text labels or icons.
