#090494

General Information about #090494

The hex color code #090494 represents a dark shade of blue, often referred to as Ultramarine. In the RGB color model, it is composed of 3.53% red, 1.57% green, and 58.04% blue. This combination results in a color that is perceived as deep, rich, and somewhat mysterious. Ultramarine historically comes from the pigment made by grinding lapis lazuli into a powder. The color is often associated with royalty, wisdom, and spirituality due to its historical rarity and expense. Its usage can evoke feelings of depth, intelligence, and calmness. In web design and graphic arts, ultramarine can add a sense of sophistication and elegance, but care should be taken to ensure sufficient contrast with other elements for accessibility.

The color #090494, a deep ultramarine, presents significant accessibility challenges, especially in web design. Its low luminance of 2.3 cd/m² results in poor contrast against standard white backgrounds, failing WCAG's AA and AAA compliance for normal text. Using this color for text requires careful consideration; foreground text color should be a very light hue, such as white or a light yellow (#FFFFFF or #FFFFE0), to ensure sufficient contrast for readability. For graphical elements and user interface components, a minimum contrast ratio of 3:1 is necessary, but 4.5:1 is preferable for optimal accessibility. It is advisable to use contrast checking tools during development to confirm adherence to accessibility standards. Furthermore, avoid relying solely on color to convey crucial information, as users with color vision deficiencies may not perceive the difference effectively. Providing alternative visual cues, such as labels or patterns, is essential to ensure inclusivity and usability for all users.
