About Ultramarine (#1C0098)

Ultramarine, represented by the hexadecimal color code #1C0098, is a deep and saturated shade of blue. It is a member of the blue color family, evoking feelings of serenity, stability, and wisdom. In the RGB color model, #1C0098 is composed of 11% red, 0% green, and 60% blue. The color's name, "ultramarine," originates from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally imported from overseas, specifically from lapis lazuli mines in Afghanistan. This pigment was highly valued in the Middle Ages and Renaissance for its vibrant and lasting color, often used in religious art and illuminated manuscripts. Today, ultramarine is synthetically produced, making it more accessible while retaining its distinctive deep blue hue. Its unique properties and rich history make it a popular choice in various applications.

The color #1C0098, a deep ultramarine, presents several accessibility considerations for web development. Its dark hue results in a low luminance value, meaning it requires careful pairing with text and interface elements to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Therefore, using #1C0098 as a background color necessitates light-colored text (e.g., white or a very light shade of yellow) to meet these standards. Insufficient contrast can make content difficult or impossible to read for users with visual impairments, including those with low vision or color blindness. Furthermore, avoid using #1C0098 as the sole indicator for interactive elements, as color alone should not convey meaning. Supplement color cues with text labels, icons, or ARIA attributes to provide alternative ways for users to understand the purpose of the element. Careful consideration of color combinations and alternative cues will improve the inclusivity of your web design.
