Ultramarine
General Information about #00049B
The hexadecimal color code #00049B represents a deep shade of ultramarine blue. In the RGB color model, it consists of 0 red, 4 green, and 155 blue. This translates to a dark, saturated blue hue. Ultramarine, historically derived from the precious mineral lapis lazuli, is known for its rich, intense color. In modern contexts, ultramarine is created synthetically. The color #00049B has a relatively low lightness value, making it appear dark. It evokes feelings of depth, calmness, and sophistication. Due to its low lightness, it is essential to use this color judiciously, particularly in designs where readability and accessibility are paramount. Understanding the properties of this color helps designers and artists use it effectively in various applications.
The color #00049B, a deep ultramarine, presents significant accessibility challenges. Its extremely low lightness value means that it offers very poor contrast against both white and light-colored backgrounds. Text or interactive elements using this color will be difficult or impossible for users with visual impairments to perceive. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text against its background. #00049B fails to meet these requirements with almost any practical background color. To improve accessibility, consider using lighter tints or shades of ultramarine or pairing it with a very light, high-contrast color for text and interactive elements. Ensure sufficient contrast by using contrast ratio tools to verify compliance with accessibility standards. Avoid using this color for critical information or actions without careful consideration of contrast and readability.

It is unsuitable as a primary color for text or important interface elements due to its low luminosity. When incorporating this color, designers must carefully consider the contrast ratio to ensure readability and accessibility for all users, particularly those with visual impairments.
