Ultramarine
General Information about Ultramarine
The hex color #000D9B, also known as Ultramarine, is a deep and intense shade of blue. It belongs to the blue color family and is characterized by its strong presence and depth. In the RGB color model, it is composed of 0% red, 5.1% green, and 61.2% blue. This specific combination creates a color that evokes feelings of trust, stability, and sophistication. Ultramarine, in its pigment form, was historically derived from lapis lazuli, making it a prized and expensive color used in art and decoration. Its association with royalty and importance continues to this day. The color is often used to represent the depths of the ocean or the vastness of the night sky.
The color #000D9B, a deep ultramarine, presents significant accessibility challenges. Its very low lightness value (around 2%) means it offers minimal contrast against light backgrounds, making text or UI elements rendered in this color difficult to read for users with visual impairments. According to WCAG guidelines, it would fail most contrast ratio tests against white or light gray. To improve accessibility, consider using this color sparingly and always paired with very light colors (white or very light grays) for text and interactive elements. Alternatively, use a much lighter tint of ultramarine or a completely different, higher-contrast color palette to ensure readability for all users, including those with low vision or color blindness. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text.

Applications
Website Design
Ultramarine, with its depth and sophistication, lends itself beautifully to website designs aiming for a luxurious or trustworthy feel. Consider using it for headers, accents, or background elements, paired with lighter neutrals to ensure readability. It's particularly effective in financial or corporate websites where conveying stability and professionalism is key. However, use sparingly as a background for text, as its low lightness can cause readability issues.
Beauty and Cosmetics
In the realm of beauty and cosmetics, ultramarine can be incorporated into eyeshadows, eyeliners, and nail polishes to create striking, bold looks. Its rich pigment adds depth and intensity to eye makeup, making it ideal for evening wear or special occasions. When used in nail polish, it offers a sophisticated alternative to traditional navy or black. It's often combined with metallic or shimmering finishes for added dimension.
Fashion Design
In fashion, ultramarine can be a captivating choice for evening gowns, suits, or statement accessories. Its regal quality makes it suitable for formal wear, while its versatility allows it to be incorporated into casual outfits as well. A silk blouse in ultramarine can elevate a pair of jeans, while an ultramarine blazer can add a touch of sophistication to a work ensemble. The color pairs well with neutrals like gray, black, and white, as well as complementary colors like gold or orange.
