General Information about Ultramarine

The color #15169F, also known as Ultramarine, is a deep, vivid shade of blue. It is situated in the blue color spectrum, exhibiting a strong presence and depth. Historically, Ultramarine pigment was derived from the rare and expensive mineral lapis lazuli, making it highly prized, especially during the Renaissance. The name "Ultramarine" literally means "beyond the sea," reflecting its origin from minerals imported to Europe from distant lands. In modern color theory, Ultramarine is often associated with feelings of tranquility, stability, and depth. It is frequently used to evoke a sense of trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven. In art and design, it can add a touch of elegance and sophistication to a variety of applications.

The color #15169F, a deep ultramarine, presents significant accessibility challenges, especially for users with visual impairments. Its low luminance value necessitates careful consideration of contrast ratios when used for text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against its background. Given the darkness of this color, it's crucial to pair it with very light hues like white or very pale yellows to ensure readability. Using tools to check color contrast is highly advised during development. Also, avoid using this color as the sole indicator for interactive elements or conveying important information, as users with color vision deficiencies may struggle to distinguish it. Providing alternative visual cues, such as underlines, icons, or patterns, enhances usability for a broader audience.
