General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #00079B, is a deep and intense shade of blue. Derived from the Latin 'ultramarinus,' meaning 'beyond the sea,' it historically referred to the pigment made from ground lapis lazuli imported from Afghanistan. This pigment was highly valued and often reserved for important works of art, particularly those depicting religious figures. In modern color theory, Ultramarine is considered a cool color, often associated with feelings of calmness, trust, and authority. Its RGB values are R:0, G:7, B:155, indicating a negligible amount of red and green, with a significant presence of blue. In the CMYK color model, it is composed of approximately 100% cyan, 95% magenta, 0% yellow, and 39% black. This composition contributes to its deep and saturated appearance. Ultramarine is widely used in various applications, from web design and graphic arts to fashion and interior decor, often employed to convey a sense of sophistication and stability.

The color #00079B, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value (very dark) results in poor contrast against white or light backgrounds, making text or interactive elements difficult to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Ultramarine falls far short of these recommendations when paired with many common background colors. To improve accessibility, it is crucial to use Ultramarine with very light foreground colors that provide sufficient contrast. Consider increasing the size of text rendered in Ultramarine to enhance readability. Providing alternative color schemes or allowing users to customize the color display can further improve the user experience for individuals with diverse visual needs. Careful consideration of color pairings and adherence to accessibility guidelines are essential when incorporating Ultramarine into designs to ensure inclusivity.
