#1F0197

General Information about Ultramarine

Ultramarine, represented by the hex code #1F0197, is a deep, vivid blue color reminiscent of the pigment derived from the mineral lapis lazuli. Historically, ultramarine was highly valued and expensive, making it a prized color in art. The name "ultramarine" literally means "beyond the sea," referring to the fact that the pigment was imported into Europe from Asia by sea. Today, synthetic versions of ultramarine are widely available, making it more accessible for various applications. This color evokes feelings of depth, tranquility, and sophistication. Its strong presence makes it ideal for use in designs where a sense of richness and formality is desired, while also carrying undertones of mystery and the unknown. It is a color commonly associated with royalty, wisdom, and spirituality.

The color #1F0197, also known as Ultramarine, presents some accessibility challenges, particularly in web design. Its dark hue results in a low luminance value, which means it needs to be paired with very light text to meet 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. Using #1F0197 as a background color requires careful selection of foreground text colors to ensure readability for users with visual impairments. It's advisable to use contrast checking tools to verify that the chosen color combination meets accessibility standards. Avoid using this color for important interactive elements if sufficient contrast cannot be achieved, as this can exclude users. Using a lighter shade of Ultramarine or a contrasting color for interactive parts are possible solutions. Consider providing alternative color schemes for users who need them.
