Ultramarine has a long history in art and design, dating back to its use in ancient pigments.

Its unique and rich hue makes it a valuable addition to many design palettes.

The color #0A019A, a deep ultramarine, presents significant accessibility challenges. Its very low luminance results in extremely poor contrast against common background colors like white, making text and interactive elements nearly illegible for users with visual impairments. To ensure accessibility, it's crucial to pair this color with very light hues, ideally near-white shades, for text or interface elements. Meeting WCAG (Web Content Accessibility Guidelines) contrast ratios is essential. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Using tools to check contrast ratios and simulating the experience for users with different visual impairments can greatly improve the inclusive design of any digital content incorporating this color. Furthermore, relying solely on color to convey information should be avoided; supplementary cues such as text labels or icons are necessary for broader accessibility.
