It falls under the category of blue colors in the color spectrum and is characterized by its high saturation and relatively low brightness. Historically, ultramarine pigment was derived from the precious mineral lapis lazuli, making it one of the most expensive and highly valued pigments used by Renaissance artists. The name 'ultramarine' literally means 'beyond the sea,' referring to its origin from overseas sources.

In color psychology, ultramarine is often linked to feelings of calmness, stability, and trust.

The color #0A0F8E, also known as Ultramarine, presents some accessibility challenges, particularly in web design. Its dark hue results in low contrast against lighter backgrounds, which can make text or interface elements difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for readability. To ensure accessibility, it's recommended to use #0A0F8E with very light backgrounds or pair it with high-contrast text colors like white or bright yellow. Careful consideration of font sizes and weights can also help improve legibility. Additionally, providing alternative text descriptions for images using this color is essential for users who rely on screen readers. Thorough testing with accessibility evaluation tools is advised to validate the color's compliance with accessibility standards, promoting an inclusive user experience for everyone.
