Ultramarine
General Information about Ultramarine
Ultramarine, represented by the hex code #18108B, is a deep blue pigment derived originally from the mineral lapis lazuli. The name 'ultramarine' comes from the Latin 'ultramarinus,' meaning 'beyond the sea,' because the pigment was imported into Europe from Asia. Chemically, it is a complex sulfur-containing sodium aluminosilicate. In the RGB color model, #18108B is composed of 9.41% red, 6.27% green, and 54.51% blue. In the CMYK color model, it consists of 83% cyan, 88% magenta, 0% yellow, and 45% black. This color is often associated with royalty, wisdom, and spirituality, adding depth and sophistication to designs.
The color #18108B, a deep ultramarine, presents significant accessibility challenges, particularly in text-based contexts. Its low lightness value of approximately 7% means that it offers insufficient contrast against standard white backgrounds, making text difficult to read for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color likely fails to meet these standards against white. To improve accessibility, consider using lighter text colors like white, yellow, or light gray on this background, or alternatively, lighten the background color itself. Tools for checking color contrast ratios are readily available online and can help ensure compliance with accessibility standards.

Applications
Interior Design
Ultramarine, with its regal and sophisticated feel, can be used to create a luxurious and calming atmosphere. It pairs well with neutral colors like gray, beige, and white, as well as metallic accents such as gold and silver, to create a balanced and elegant space. Consider using it as an accent wall color, for upholstery, or for decorative accessories to add depth and character to a room.
Fashion and Beauty
Ultramarine is a classic and versatile color that can be used to create a variety of looks, from sophisticated and elegant to bold and eye-catching. It can be paired with other jewel tones for a rich and luxurious look, or with lighter colors for a more casual and breezy feel. Consider using it for dresses, skirts, tops, or accessories to add a touch of color and personality to your wardrobe. The deep color also works well in makeup, particularly eyeshadow and eyeliner, to create a dramatic and alluring look.
Web Development
In web development, ultramarine can be used strategically to draw attention to important elements, establish a sense of trust and authority, or complement other brand colors. Given its darkness, ensure sufficient contrast with text and other elements. It works well for call-to-action buttons, headings, or background accents, especially when paired with lighter, complementary colors. Consider using it to create a sense of depth and sophistication in your web design.
