Ultramarine
General Information about Ultramarine
Ultramarine, represented by the hexadecimal color code #1F0EA5, is a deep blue pigment derived from the mineral lapis lazuli. Historically, it was highly valued and often more expensive than gold, making it a color reserved for royalty and religious figures in art. Its intense, rich hue is due to the presence of sulfur-containing compounds within the mineral's crystal structure. Today, synthetic ultramarine is widely available, offering the same vibrant color at a fraction of the cost. In color theory, ultramarine is considered a cool color, associated with feelings of tranquility, stability, and wisdom. It is widely used in various applications, including art, design, and manufacturing, due to its captivating appearance and symbolic connotations. Its spectral reflectance is low in the red and green regions, resulting in the perception of deep blue.
The color #1F0EA5, a deep ultramarine, presents some accessibility challenges. Its low luminance value of approximately 3% means it requires careful consideration when used as a foreground color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against its background. Given its darkness, #1F0EA5 necessitates a very light background to meet these standards. Using it with text sizes smaller than 18pt (or 14pt bold) is strongly discouraged unless paired with an adequately contrasting color. Additionally, avoid using it to convey crucial information without redundant cues, as those with visual impairments may struggle to differentiate it from similar dark shades. Consider providing alternative visual cues, such as icons or text labels, to ensure inclusivity.

Applications
Web Design
In web design, ultramarine can be used as a strong accent color for headings, buttons, or navigation menus to draw attention to key elements. It evokes a sense of trust and stability, making it suitable for finance or technology websites. However, care must be taken to ensure sufficient contrast with the background, especially for text, to maintain accessibility. For example, pairing it with a light yellow or white can create a visually appealing and accessible design. Also, it should be used sparingly and deliberately to create visual hierarchy without overwhelming the user.
Fashion
In fashion, ultramarine can be used as a bold statement color, especially in evening wear or accessories. It pairs well with neutral colors like black, white, and gray, as well as metallic accents like gold or silver. A small ultramarine bag or shoe can add a pop of color to a neutral outfit. For those who like contrast, combining this color with a vibrant orange or yellow creates a stunning look that captures attention and radiates self-assurance. Its rich depth is perfect for adding a touch of elegance.
Interior Design
Ultramarine is a superb choice for creating sophisticated and calm interiors. It works wonderfully as an accent wall in living rooms or bedrooms, particularly when combined with neutral tones like beige, gray, or off-white. The rich blue hue can create a calming and relaxing atmosphere, ideal for promoting relaxation and peace. Additionally, this color complements natural materials such as wood, stone, and linen, bringing a sense of nature inside the room. It is also useful in decorations like rugs, curtains, or cushions to create a harmonic and chic feel.
