#09158E

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #09158E, is a deep and intense shade of blue. Historically, ultramarine was derived from the precious gemstone lapis lazuli, making it one of the most expensive and highly valued pigments. The name itself, "ultramarine," means "beyond the sea," reflecting its origin as a pigment imported from distant lands. Its rich and saturated tone has been favored by artists throughout history, particularly during the Renaissance, for its ability to render vibrant and luminous blues in paintings. Today, synthetic ultramarine is widely available, but the color retains its association with luxury and sophistication.

The color #09158E, a deep shade of ultramarine, presents significant accessibility challenges, particularly in web design. Its low luminance makes it difficult to read against lighter backgrounds, potentially violating WCAG contrast ratio guidelines. For text, a very light color such as #FFFFFF or #F0F0F0 is strongly advised to ensure readability for users with visual impairments. When used for interactive elements, ensure sufficient contrast in states like hover, focus, and active to provide clear visual cues. Avoid pairing this color with other dark shades, as this will further reduce visibility. Employing color contrast checkers is essential to confirm compliance with accessibility standards and offer a positive user experience for everyone.
