#180CA8

General Information about Ultramarine

Ultramarine, represented by the hex code #180CA8, is a deep blue pigment derived from the mineral lapis lazuli. Its name comes from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally imported to Europe from Asia. This color is highly valued for its rich, intense hue and has been used in art and decoration for centuries. In color theory, ultramarine is considered a cool color, often associated with feelings of tranquility, depth, and stability. In modern applications, ultramarine is used in web design, graphic design, and various artistic mediums. Its perceived psychological effects include promoting feelings of calmness and focus, making it suitable for environments where concentration is required. However, using #180CA8 requires careful consideration due to its low lightness value, which can pose accessibility challenges if not properly addressed.

The color #180CA8, a deep ultramarine, presents significant accessibility challenges. Its low lightness value (around 6%) means it offers very poor contrast against white text. This fails WCAG (Web Content Accessibility Guidelines) standards for both normal and large text sizes. To improve accessibility, consider using lighter text colors like white (#FFFFFF) or very light grays. However, even with white text, careful consideration of text size and weight is crucial. A thicker font weight can somewhat improve readability. A better approach would be to use #180CA8 for larger graphical elements or as a background color with much lighter foreground elements. Avoid using it for essential text or interactive elements without sufficient contrast to ensure users can perceive the information. Always test color combinations with accessibility tools to ensure compliance with WCAG guidelines and to cater to users with visual impairments.
