General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0C128C, is a deep blue color that evokes feelings of stability, trust, and intelligence. It is often associated with royalty, wisdom, and the night sky. In color psychology, blue is known for its calming and soothing properties, making it a popular choice for brands and designs that aim to create a sense of tranquility and reliability. Ultramarine is a relatively dark shade, with low saturation and brightness values, contributing to its serious and sophisticated character. The color is composed of 4.71% red, 7.06% green, and 54.9% blue. It is important to consider its low luminosity when using it in designs to ensure sufficient contrast with text and other elements.

The color #0C128C, also known as Ultramarine, presents some accessibility challenges, especially in web design. Its dark hue means that text or other elements displayed in this color require very light foreground colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using a color like white (#FFFFFF) or a very light gray on an Ultramarine background can help meet these contrast requirements. However, designers should always test their color combinations with accessibility tools to confirm compliance. If adequate contrast cannot be achieved, it may be necessary to adjust the background color or choose a different color combination altogether to ensure readability and usability for all users, including those with visual impairments.
