#06009B

General Information about Ultramarine

Ultramarine, represented by the hex code #06009B, is a deep, saturated blue color that evokes feelings of depth, stability, and sophistication. Historically, ultramarine was derived from the precious gemstone lapis lazuli, making it one of the most expensive and highly prized pigments during the Renaissance. Its name literally means 'beyond the sea,' reflecting its origin from stones imported into Europe from Asia. In modern color theory, ultramarine is considered a primary color in subtractive color models (CMYK), and it plays a vital role in color mixing and achieving accurate color reproduction. In digital design, understanding the RGB values (6, 0, 155) is crucial for ensuring consistency across different displays and devices. The color carries cultural significance, often associated with royalty, religious iconography, and artistic expression. Its intense hue can create a sense of drama or serenity depending on its application.

The hex color #06009b, a deep ultramarine, presents significant accessibility challenges, primarily due to its low luminance. When used as a background color, it demands very light text to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Given the darkness of #06009b, achieving these ratios requires careful selection of text colors, leaning towards white or very light shades of yellow or green. It is crucial to test color combinations with accessibility tools to verify compliance. Moreover, avoid using this color for crucial UI elements like buttons or links without providing clear visual cues, such as borders or icons, to aid users with visual impairments. Considering alternative, lighter shades of blue or using color combinations that naturally offer higher contrast can improve the overall accessibility of a design.
