General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #190A91, is a deep blue-purple hue. Historically, ultramarine was derived from the rare and expensive mineral lapis lazuli, making it a highly valued pigment, especially in Renaissance painting. The name "ultramarine" literally means "beyond the sea," reflecting its origin from overseas sources. In color theory, ultramarine is considered a cool color, associated with depth, stability, and intelligence. In modern applications, synthetic ultramarine pigments provide an affordable alternative while retaining the characteristic vibrant color. It is now widely used in various fields, including art, cosmetics, and plastics, due to its strong tinting strength and lightfastness. It can be combined with other colors to produce different shades.

The color #190A91, Ultramarine, presents accessibility challenges due to its dark hue. When used as a background color, it requires very light text (ideally white or near-white) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Without adequate contrast, users with visual impairments may struggle to distinguish text from the background. Similarly, when used for text, a light background is essential. Using color contrast tools can help designers verify compliance with accessibility standards, ensuring content is usable by a wider audience. Consider providing alternative color schemes or a user-adjustable contrast setting to enhance accessibility.
