General Information About Ultramarine

Ultramarine, represented by the hexadecimal color code #2105AE, is a deep blue pigment traditionally derived from lapis lazuli. The name comes from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was imported to Europe from Asia. Chemically, it's a complex sodium aluminosilicate containing sulfur. Historically prized for its brilliance and permanence, ultramarine was one of the most expensive pigments available, often reserved for depicting religious figures, particularly the Virgin Mary's robes. Today, synthetic ultramarine is widely available, offering the same vibrant hue at a more affordable price. In color theory, ultramarine is considered a cool color, often associated with calmness, depth, and wisdom. Its intense saturation makes it a visually striking color, suitable for various applications from art to design.

The color #2105AE, also known as Ultramarine, presents several accessibility considerations for web developers. Due to its deep, saturated nature, it's imperative to ensure sufficient contrast when pairing it with text or other interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular). Using a color contrast checker can help determine if the chosen foreground color meets these standards. Avoid using this color for small, critical elements if contrast cannot be adequately achieved. When using Ultramarine, consider users with low vision or color blindness. Provide alternative cues, such as icons or text labels, to convey information that might otherwise be solely dependent on color. Furthermore, ensure that interactive elements, like buttons or links, have clear visual indicators when they are focused or hovered over, to aid users navigating with assistive technologies. Proper implementation of ARIA attributes can also improve the accessibility of complex user interface components.
