Ultramarine

General Information about Ultramarine

The hex color #200791, also known as Ultramarine, is a deep and vibrant shade of blue. In the RGB color model, it is composed of 12.55% red, 2.75% green, and 56.86% blue. This combination results in a color that evokes feelings of tranquility, depth, and sophistication. Historically, ultramarine was derived from the precious stone lapis lazuli, making it one of the most expensive pigments used in painting, often reserved for depicting the robes of the Virgin Mary and other important figures. Today, synthetic versions make it more accessible, but it still retains its association with luxury and quality. Its use in design and art can create a sense of elegance and visual interest. The color is often favored for its ability to evoke feelings of calm and stability, making it suitable for various applications.

The color #200791, a deep ultramarine, presents several accessibility considerations for web design. Its dark hue provides excellent contrast against white or very light backgrounds, ensuring readability for users with visual impairments. However, using it as a background color necessitates light text to maintain sufficient contrast. When paired with other dark colors, contrast can drop below WCAG guidelines, making text difficult to read. Therefore, careful selection of foreground and background color combinations is crucial. Tools for contrast checking are essential to ensure compliance with accessibility standards, aiming for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Furthermore, avoid using this color as the sole indicator of interactive elements; supplement it with text labels, icons, or underlines to support users with color vision deficiencies. Thoughtful application will allow the color to enhance the visual appeal without compromising accessibility.

Applications

• Web Design Accent

  In web design, ultramarine can be used for headers and navigation bars to create a sophisticated and calming user experience. It’s particularly effective for websites targeting professional or academic audiences, where a sense of trust and stability is desired. Using it sparingly as an accent color against a lighter background can draw attention to key elements without overwhelming the user. For example, buttons, links, or icons could benefit from the visual pop offered by this deep blue. However, careful consideration must be given to contrast ratios to ensure accessibility for all users, especially those with visual impairments. Complementary colors should be chosen strategically to balance the richness of the ultramarine, creating a harmonious visual composition.

• Interior Design Accent

  In interior design, ultramarine can be used as a striking accent color for walls or furniture to introduce a touch of elegance and depth to a space. It works particularly well in rooms with ample natural light, where its richness can be fully appreciated. Pairing it with neutral tones like beige or gray can create a balanced and sophisticated atmosphere. Consider using it for accent walls, upholstery, or decorative accessories such as cushions and throws. Metallic accents, such as gold or silver, can further enhance its luxurious feel. The key is to use it judiciously to avoid overwhelming the space and to create a harmonious blend with other design elements.

• Fashion Accent

  In fashion, ultramarine can be incorporated into garments as a statement color or used for accessories to add a pop of sophistication to an outfit. A solid ultramarine dress or blazer can exude confidence and style, while a scarf or handbag in this hue can elevate a more neutral ensemble. When pairing ultramarine with other colors, consider complementary shades like gold or yellow to create a vibrant contrast, or opt for analogous colors like blue-green or violet for a more subdued look. For evening wear, fabrics with a slight sheen or embellishments can enhance its luxurious appearance, making it a versatile choice for a range of occasions.
