About Ultramarine

Ultramarine, represented by the hex code #0001A0, is a deep blue color known for its rich and intense hue. Historically, ultramarine was derived from the precious stone lapis lazuli, making it a highly valued pigment used in Renaissance paintings and other artistic applications. Today, it is synthetically produced, making it more accessible and affordable. The color evokes feelings of depth, serenity, and sophistication. In color psychology, blue is often associated with trust, stability, and intelligence. Ultramarine's unique depth makes it suitable for creating a sense of elegance and luxury. However, due to its darkness, it should be used thoughtfully in design to ensure readability and contrast.

The hex color #0001A0, Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value (very close to black) results in poor contrast against white backgrounds. Consequently, text or interactive elements using this color may be illegible for many users. To ensure accessibility, it is crucial to pair Ultramarine with very light colors, such as white or pale yellow, to achieve a contrast ratio that meets WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. Using tools to check color contrast is essential. Avoid using #0001A0 for critical information or interactive elements without careful consideration of its impact on users with disabilities. Providing alternative high-contrast themes can further enhance accessibility.
