Ultramarine

#040098

General Information about Ultramarine

Ultramarine, represented by the hex code #040098, is a deep, rich blue color that derives its name from the pigment originally made from lapis lazuli. This pigment was highly valued in the past, often more expensive than gold, and reserved for the most important commissions, such as the robes of the Virgin Mary in religious paintings. Today, synthetic ultramarine is widely available, making it a more accessible color for various applications. It is located in the blue region of the color spectrum, possessing a strong, saturated quality. This color conveys feelings of depth, stability, and sophistication, and is often associated with royalty and wisdom.

The color #040098, a deep ultramarine, presents significant accessibility challenges, especially in web design. Its extremely low luminance (very dark) means it requires very light text (white or near-white) to achieve sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is necessary for normal text and 3:1 for large text to meet AA compliance. Using #040098 for text on a white background, or conversely, white text on a #040098 background, should be carefully evaluated. Ensure proper contrast using online contrast checkers. Avoid using this color for essential interactive elements or small text where readability is paramount. Consider providing alternative high-contrast themes for users with visual impairments.
