Ultramarine

#190F89

General Information about Ultramarine

Ultramarine, represented by the hex code #190F89, is a deep, saturated blue color historically derived from the pigment made of ground lapis lazuli. The name "ultramarine" comes from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally imported to Europe from Asia. This color evokes feelings of depth, tranquility, and sophistication. In color psychology, deep blues like ultramarine are often associated with stability, confidence, and intelligence. Its high saturation and relatively low brightness make it suitable for accent elements or backgrounds when paired with lighter colors to provide sufficient contrast. The color also has a rich history of use in art and design.

The color #190F89, a deep ultramarine, presents significant accessibility challenges, particularly in text-based applications. Its low luminance of 3.3 cd/m² results in poor contrast against common background colors like white. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This color would likely fail these criteria when paired with light backgrounds, making it difficult for users with visual impairments to read. To improve accessibility, consider using a lighter tint of ultramarine or pairing it with a much lighter color for sufficient contrast. Tools like contrast checkers can help evaluate and adjust color pairings to ensure they meet accessibility standards, promoting inclusivity in design and web development.
