#1115A3

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1115A3, is a deep, vivid shade of blue, closely associated with the pigment derived from lapis lazuli. Historically, it was one of the most expensive and highly prized blue pigments, often reserved for important figures and artwork. In modern color theory, Ultramarine evokes feelings of trust, intelligence, and stability. Its deep hue makes it suitable for conveying a sense of authority and sophistication. In digital applications, Ultramarine can be used to create a sense of depth and richness in designs, although careful consideration must be given to accessibility due to its relatively low luminance. The color sits between blue and violet on the color spectrum and is non-metallic.

The color #1115A3, also known as Ultramarine, presents some accessibility challenges, particularly in text-based contexts. Due to its dark hue and relatively low luminance, it can create insufficient contrast when paired with lighter colors, especially white or light gray. This can make text difficult to read for individuals with visual impairments or colorblindness. To ensure optimal accessibility, it's crucial to use #1115A3 with significantly lighter background colors, achieving a contrast ratio that meets WCAG (Web Content Accessibility Guidelines) standards of at least 4.5:1 for normal text and 3:1 for large text. Alternatively, employing #1115A3 sparingly for decorative elements or graphical components, rather than crucial text, can mitigate accessibility issues. When used as a background color, ensure that the foreground text is light enough to provide sufficient contrast. Tools such as contrast checkers can be invaluable in evaluating and optimizing color combinations for accessibility. Additionally, consider providing alternative color schemes that offer better contrast for users with specific visual needs.
