General Information about Ultramarine (#180497)

Ultramarine, represented by the hexadecimal color code #180497, is a deep, intense shade of blue. Historically, Ultramarine was a pigment derived from lapis lazuli, a rare and expensive mineral, making it highly valued, especially in Renaissance painting. Today, synthetic versions are widely available, but the name persists, evoking a sense of richness and depth. In color psychology, Ultramarine is often associated with qualities such as wisdom, intelligence, trust, efficiency, serenity, and loyalty. It is considered a stable and calming color, making it suitable for creating a sense of peace and order. Its high saturation and dark value make it a bold choice that can add depth and drama to various applications, from graphic design to interior decor.

The accessibility of #180497 (Ultramarine) is limited due to its dark nature. When used as a background color, it necessitates very light text (white or near-white) to ensure sufficient contrast for readability, ideally exceeding the WCAG's minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. Using it for text on a white background is not recommended due to the poor contrast. In user interface design, avoid using it for crucial interactive elements unless accompanied by clear visual cues and sufficient contrast. When incorporating this color, consider users with visual impairments and provide alternatives like adjustable color schemes or high-contrast modes. Ensure proper color contrast analysis is performed with accessibility evaluation tools. It's best used sparingly as an accent color rather than for large surfaces or critical text elements.
