General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0912AB, is a deep and intense shade of blue. Historically, ultramarine was derived from the rare and expensive mineral lapis lazuli, making it a highly prized pigment, especially during the Renaissance period for paintings and other artistic creations. Its rich and vibrant hue quickly made it a favorite among artists. Today, synthetic ultramarine is widely available, retaining the color's characteristic depth and brilliance without the exorbitant cost. In color theory, ultramarine is considered a cool color, often associated with feelings of tranquility, stability, and wisdom. Its position on the color wheel places it between blue and violet, exhibiting qualities of both.

The color #0912AB, a deep ultramarine, presents several accessibility considerations. Due to its low luminance, it requires careful pairing with contrasting colors to ensure readability, especially for text. A light text color, such as white or a pale yellow, is necessary to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. Using this color as a background for extensive text blocks may strain the eyes of some users. When using it for interactive elements like buttons or links, ensure sufficient size and clear visual cues, such as hover effects, to aid users with visual or motor impairments. Consider providing alternative themes or color choices to cater to users with specific visual needs, like those with color blindness or low vision. Thorough testing with accessibility tools is recommended to validate the color's usability across different user groups and platforms. The color should not be used as the sole indicator for important information or actions.
