Ultramarine
General Information about Ultramarine
Ultramarine, represented by the hexadecimal color code #180D8B, is a deep, intense shade of blue. Historically, ultramarine was derived from the precious gemstone lapis lazuli, making it one of the most expensive pigments during the medieval and Renaissance periods. Its name, meaning "beyond the sea," reflects its origin as it was imported to Europe from mines in Afghanistan. Today, ultramarine is synthetically produced, making it more accessible. It is valued for its non-toxic properties, excellent lightfastness, and resistance to fading. This color is often associated with royalty, wisdom, and spirituality. In color psychology, ultramarine is thought to evoke feelings of calm, peace, and serenity.
The color #180D8B, a deep ultramarine, presents several accessibility considerations for web developers. Its low luminance of 4.54 cd/m² results in a very low contrast ratio against white backgrounds, failing WCAG standards for normal text (4.5:1) and large text (3:1). This means text in #180D8B is challenging to read for users, especially those with visual impairments. To improve accessibility, pair it with very light colors like whites or very light yellows for text, or use it sparingly for decorative elements. Also, provide sufficient contrast in interactive elements such as buttons or links. Avoid using it for crucial information without ensuring a high contrast ratio. Consider using color contrast checking tools during the design process to validate accessibility and ensure the content is usable by a wide audience. If #180D8B is a must-use color, consider increasing font size or boldness to enhance readability, but contrast remains the key factor.

Applications
Web Design
In web design, ultramarine can be used as a secondary color for backgrounds or accents. Its depth creates a sense of sophistication and calm. It's suitable for websites targeting professional or academic audiences. However, due to accessibility concerns, it should not be used as a primary text color unless paired with a very light background. Consider using it for headers, decorative elements, or call-to-action buttons with sufficient contrast. Ultramarine can evoke feelings of trust, authority, and stability when applied thoughtfully.
Fashion
In fashion, ultramarine serves as a bold statement color, often used in evening wear or formal attire. Its richness adds a touch of elegance and luxury. It can be paired with neutral tones like gray or black for a sophisticated look, or with contrasting colors like gold or yellow for a more vibrant effect. Ultramarine is particularly flattering on individuals with cool skin tones. This colour conveys confidence and a sense of refined taste.
Interior Design
In interior design, ultramarine can be used to create a focal point in a room, such as an accent wall or a statement piece of furniture. It pairs well with warm neutrals like beige or cream, as well as metallic accents like gold or brass. It is suitable for spaces where a sense of tranquility and sophistication is desired, such as bedrooms or home offices. Use it sparingly to avoid overwhelming the space and creating a gloomy atmosphere.
