General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #031598, is a deep, intense blue hue. It's derived from the pigment lapis lazuli, a semi-precious stone that has been ground into powder since the 6th and 7th centuries. The name 'ultramarine' literally means 'beyond the sea,' as the pigment was originally imported to Europe from mines in Asia. In the RGB color model, #031598 consists of 1.2% red, 8.24% green, and 59.61% blue. In the CMYK color model, which is used for printing, it is composed of 99% cyan, 86% magenta, 0% yellow, and 40% black. Ultramarine is often associated with royalty, wisdom, and spirituality due to its historical significance and the cost associated with its production. Today, synthetic ultramarine is readily available and widely used in paints, inks, and plastics.

The hex color #031598, a deep ultramarine, presents significant accessibility challenges. Its low lightness value results in poor contrast against light backgrounds, making text and interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. This color is unlikely to meet those requirements when paired with standard white or light gray backgrounds. Web developers should avoid using this color for text or essential interface components unless paired with a very light color. Using color contrast tools is crucial to ensure sufficient contrast and avoid accessibility barriers. Considering alternative, lighter shades or using this color sparingly for decorative elements only are recommended strategies to improve accessibility.
