General Information about Ultramarine

Ultramarine, represented by the hex code #180692, is a deep, rich blue color historically derived from the precious gemstone lapis lazuli. Its name literally means "beyond the sea," reflecting its origin as a pigment imported to Europe from Asia. Chemically, modern ultramarine is a complex sodium aluminosilicate containing sulfur, giving it its characteristic hue. In color theory, ultramarine is considered a cool color, often associated with calmness, depth, and stability. It evokes feelings of serenity and trust, making it a popular choice in various applications, from art and design to branding and fashion. The pigment has been prized for centuries for its brilliance and permanence, making it a staple in artistic masterpieces.

The color #180692, a deep ultramarine, presents significant accessibility challenges, especially in web design. Its low luminance makes it difficult to read when used as text on a white background, failing WCAG's contrast ratio guidelines for text. To improve accessibility, consider using it sparingly for decorative elements rather than essential text. When used for text, pair it with very light colors like white or bright yellows to ensure sufficient contrast. Alternatively, use a lighter tint of #180692 or a completely different color scheme that provides better contrast for users with visual impairments. Remember that colorblind users might perceive this color differently, so always test your designs with colorblindness simulators to ensure content remains understandable for everyone. Providing alternative cues like icons or text labels can further enhance accessibility.
