It is composed of 3.5% red, 3.92% green, and 73.33% blue. In the RGB color space, Ultramarine is created by combining these primary colors, while in the CMYK color space, it is achieved through a mixture of cyan, magenta, and black inks.

The hex color #090FAB, Ultramarine, presents accessibility challenges, especially when used as a text color on a white background. Its low luminance contrast ratio necessitates careful consideration of foreground and background color pairings. Web Content Accessibility Guidelines (WCAG) recommend a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Ultramarine often falls short of these recommendations, potentially making content difficult to read for users with visual impairments. To improve accessibility, consider using Ultramarine sparingly for decorative elements rather than essential text, or pair it with lighter shades to increase contrast. Offering alternative high-contrast themes or color customization options will improve accessibility for a wider audience. Providing sufficient contrast ensures that content is perceivable to users with varying visual abilities and meets accessibility standards.
