About Ultramarine (#0a098e)

Ultramarine is often associated with qualities like depth, stability, and wisdom. Historically, the pigment for Ultramarine was derived from the gemstone lapis lazuli, making it a highly prized and expensive color, often reserved for depicting important figures or religious scenes in art. In contemporary usage, Ultramarine is used across various design fields to evoke feelings of trust, authority, and sophistication.

Understanding the history and psychological associations of Ultramarine can help designers effectively use it to convey specific messages and create impactful visual experiences.

The hex color #0a098e, also known as Ultramarine, presents significant accessibility challenges due to its dark hue. When used as a background color, it requires very light text (white or near-white) 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. Ultramarine may struggle to meet these ratios with many common text colors, potentially causing visual strain for users, especially those with visual impairments. Therefore, careful consideration is needed when pairing this color with text or interactive elements to ensure accessibility compliance and a positive user experience. Using tools to measure color contrast is highly advised.
