General Information about Ultramarine

Ultramarine, represented by the hex code #0B0E8D, is a deep, rich blue color that evokes feelings of sophistication, depth, and tranquility. Historically, ultramarine pigment was derived from lapis lazuli, making it a precious and highly valued color, especially during the Renaissance period. Today, it is synthetically produced, making it more accessible, but it still retains its association with luxury and artistry. In color psychology, ultramarine is often associated with intelligence, stability, and unity. It is considered a calming color that promotes introspection and relaxation. Its dark and intense nature makes it a versatile choice for various applications, ranging from web design to fashion.

The hex color #0B0E8D, a deep shade of ultramarine, presents some accessibility challenges, particularly when used as a background or text color. Its low luminance value means it needs to be paired with very light text (white or near-white) to ensure sufficient contrast for readability, adhering to WCAG guidelines. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When used for interactive elements like buttons, it's crucial to provide clear visual cues for focus states and hover effects, perhaps using a lighter shade of blue or a contrasting color. Proper color contrast benefits users with visual impairments, including those with low vision or color blindness. Tools like WebAIM's contrast checker can help verify compliance. Moreover, avoid using this color as the sole indicator of important information; supplement it with text labels or icons to ensure accessibility for all users.
