Ultramarine

#00009C

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #00009C, is a deep, vivid blue that evokes feelings of sophistication, depth, and tranquility. Historically, the pigment for ultramarine paint was derived from the semi-precious stone lapis lazuli, making it a highly prized and expensive color, often reserved for the most important figures in paintings, such as the Virgin Mary. In modern color theory, ultramarine is valued for its ability to create strong visual impact and convey a sense of authority. It is commonly used in branding and graphic design to represent trustworthiness, stability, and intelligence. Its rich hue makes it stand out, drawing the eye and creating a lasting impression.

The color #00009C, also known as Ultramarine, presents significant accessibility challenges, particularly concerning color contrast. When used as text against a white background, it fails to meet WCAG (Web Content Accessibility Guidelines) standards for normal text (AA) and large text (AA), and even fails for AAA standards. This means users with visual impairments may struggle to read content using this color. To improve accessibility, consider pairing it with very light colors, such as whites (#FFFFFF) or light yellows (#FFFFE0) for text. If #00009C is used as a background color, ensure that the text on top has sufficient contrast, employing tools like contrast checkers to verify compliance with accessibility guidelines. Larger font sizes or bolder fonts can sometimes marginally improve contrast, but thorough testing is still crucial to ensure usability for all users.
