Ultramarine
General Information about Ultramarine
Ultramarine, represented by the hexadecimal color code #00139B, is a deep blue color reminiscent of the pigment derived from lapis lazuli. Historically, ultramarine pigment was highly prized and expensive, making it a color associated with royalty and high art. In the RGB color model, it is composed of 0% red, 7.45% green, and 61.18% blue. Its perceived coolness makes it useful for conveying feelings of tranquility and serenity. In modern applications, ultramarine is used across various fields, including digital design, fashion, and interior decoration, where its depth and richness can add a touch of sophistication. The color is most suitable for large areas, as it can appear quite dark if used in small portions.
The color #00139B, a deep ultramarine, presents some accessibility challenges, especially for users with visual impairments. Its low luminance value means that text rendered in this color requires high contrast against a light background to be legible. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as per WCAG guidelines. When using this color for interactive elements, ensure sufficient visual cues beyond color alone, such as text labels or icons. Additionally, consider providing alternative color schemes that offer better contrast for users with specific visual needs. Thorough testing with accessibility tools is crucial to validate the design's usability for all users. It's also worth considering using a lighter tint of ultramarine or a completely different color for essential interactive elements to guarantee optimal accessibility.

Web Design - Branding Accent
In web design, ultramarine can be used sparingly to create a sense of sophistication and trust. It's suitable for header backgrounds, call-to-action buttons, or as an accent color in branding. However, due to its low contrast, it should be paired with lighter colors to ensure readability. Use the color to highlight parts that you want the user to pay attention to.
