The color #0f198c, also known as Ultramarine, is a deep shade of blue that evokes feelings of calmness, serenity, and sophistication. It belongs to the blue color family and is characterized by its rich, intense hue. Historically, ultramarine was derived from the rare and precious mineral lapis lazuli, making it a highly valued pigment used by artists and royalty alike. Today, it is synthetically produced but retains its association with luxury and elegance.

The hex color #0f198c, a deep ultramarine, presents some accessibility challenges, especially concerning color contrast. When used as a background color, it necessitates light-colored text to ensure readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to comply with WCAG guidelines. Tools like contrast checkers can verify compliance. Due to its darkness, this color is best suited for decorative elements or when paired with high-contrast elements to avoid visual strain for users, particularly those with visual impairments. Careful consideration should be given to the surrounding elements to maintain a balanced and accessible design. Ensure interactive elements have sufficient contrast for focus states as well.
