General Information about Ultramarine

Ultramarine, represented by the hex code #010997, is a deep blue color historically derived from the precious mineral lapis lazuli. The name "ultramarine" originates from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally imported to Europe from Asia. This color is characterized by its rich, intense hue and has been highly valued in art and decoration for centuries. In modern color theory, ultramarine is considered a primary color and is essential for color mixing. The digital representation of ultramarine allows for its precise reproduction across various media, from web design to digital art, maintaining its historical significance in contemporary applications. Its use in web design requires careful attention to contrast ratios to ensure accessibility, especially for text and interactive elements.

The hex color #010997, a deep ultramarine, presents several accessibility considerations for web developers. Its low luminance value means it requires careful pairing with text and background colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #010997 as a background, it's crucial to use very light text colors, such as white or light yellow, to meet these standards. Tools like contrast checkers can help determine if the color combinations are accessible. Furthermore, avoid relying solely on color to convey information; supplement color cues with text labels or icons to accommodate users with color vision deficiencies. Considering users with cognitive disabilities is also important; overly complex or jarring color schemes can be distracting. Therefore, use this deep blue thoughtfully and strategically to create an inclusive and accessible experience.
