Ultramarine
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.

Applications
Interactive Elements
Ultramarine can be used for primary buttons and key interactive elements to draw user attention. Its vibrant hue makes it easily noticeable, encouraging user engagement. Employing it strategically, such as for call-to-action buttons or important navigation links, can significantly enhance the user interface and improve conversion rates. It should be combined with proper contrast in the buttons to meet accesibility requirements.
Data Visualization
In data visualization, Ultramarine can effectively represent a specific category or data series. Its distinct color stands out well in charts and graphs, making it easier for users to differentiate between datasets. Using it consistently throughout the visualization ensures clarity and avoids confusion. When using Ultramarine to highlight data, it is important to consider users with visual impairments and use labels with the data points.
Fashion Design
Ultramarine, with its profound depth and richness, can be a striking choice for formal wear. Its sophisticated character evokes a sense of confidence and elegance, perfect for evening gowns, suits, or statement accessories. When paired with complementary colors such as gold or silver, or even contrasted against stark white, it creates a captivating visual impact, enhancing the overall aesthetic appeal and making a lasting impression. A single ultramarine piece can make any outfit memorable.
