#0F07AC

General Information about Ultramarine

Ultramarine, represented by the hex code #0F07AC, is a deep blue color with a rich history, originally derived from the precious gemstone lapis lazuli. The name "ultramarine" literally means "beyond the sea," referring to its origin from pigments imported into Europe from Asia. Chemically, the modern pigment is a complex sodium aluminum silicate with sulfur impurities, giving it the vibrant blue hue. In color theory, Ultramarine is considered a cool color, associated with calmness, depth, and sophistication. It has been extensively used in art, dating back to medieval paintings, and continues to be a popular choice in graphic design, fashion, and interior decoration. The color evokes a sense of trust and stability.

The color #0F07AC, also known as Ultramarine, presents several accessibility considerations for web developers. Its dark hue results in a low luminance value, which means that using it as a background color requires careful selection of foreground text to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. If used for interactive elements, the color contrast ratio should be even higher to make it easily identifiable. Developers should use color contrast checkers to verify compliance and provide sufficient visual cues for users with low vision or color blindness, such as using bold text or icons to improve distinction. Also, avoid using color as the sole means of conveying information.
