General Information about Ultramarine

The color #00019B, 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 chromaticity and low lightness. In the RGB color model, it is composed of 0% red, 0.39% green, and 61.18% blue. The name "Ultramarine" originates from the Latin "ultramarinus," meaning "beyond the sea," as the original pigment was derived from the precious gemstone lapis lazuli, which was imported from distant lands. Historically, ultramarine was highly valued and reserved for important artworks, such as those depicting religious figures. Today, synthetic ultramarine is widely available, making it more accessible for various applications, including art, design, and manufacturing. It is known for its stability and resistance to fading, ensuring long-lasting color in different mediums. The hex code #00019B is often associated with feelings of trust, loyalty, and intelligence.

The hex color #00019b, a deep ultramarine, presents significant accessibility challenges, especially in web design. Its extremely low lightness value means that text rendered in this color requires very light foreground colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using a color like #00019b for text without careful consideration of contrast can make content unreadable for users with visual impairments. To mitigate these issues, designers should pair #00019b with colors like white or very light shades of yellow or cyan. Tools that check color contrast ratios are invaluable in ensuring compliance with accessibility standards and creating inclusive designs. Thoughtful application of color is essential to provide equal access to information.
