Its name literally means "beyond the sea," reflecting its origin as a pigment imported into Europe from Asia. Today, ultramarine is synthetically produced, making it more accessible and affordable. This color is often associated with royalty, wisdom, and spirituality. In color psychology, blue generally conveys feelings of calmness, trust, and stability.

The color #0A0FAA, a deep shade of ultramarine, presents specific accessibility considerations for web developers. Its dark nature necessitates careful selection of foreground colors 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. When using #0A0FAA as a background, pairing it with light colors such as white (#FFFFFF) or very light grays is advisable. Tools like contrast checkers can help verify compliance. Furthermore, avoid relying solely on color to convey important information, as users with color vision deficiencies may not perceive the intended message. Providing alternative cues, such as text labels or icons, enhances usability for all users. Thoughtful application of this color, combined with accessibility best practices, ensures an inclusive user experience.
