General Information about Ultramarine

The color #01149A, also known as Ultramarine, is a deep, saturated shade of blue. Its name is derived from the pigment originally made from lapis lazuli, a semi-precious stone mined in Afghanistan. Historically, Ultramarine was highly prized and expensive, reserved for the most important commissions, such as the robes of the Virgin Mary in medieval paintings. Today, synthetic Ultramarine is widely available, making it a more accessible color for various applications. In color theory, Ultramarine is considered a cool color, associated with feelings of calmness, stability, and intelligence. It is often used in branding and design to convey trust and professionalism. Its hexadecimal code is #01149A, representing a combination of red, green, and blue light.

The hex color #01149A, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue results in a very low contrast ratio against a standard white background, making text and other elements difficult to read. Web developers employing this color should prioritize providing sufficient contrast by pairing it with significantly lighter colors, such as white, light gray, or pale yellow. It's also crucial to test the color combination with accessibility evaluation tools and consider the needs of users with color vision deficiencies. Providing alternative high-contrast themes or allowing users to customize the color scheme are effective strategies to improve accessibility. Ensuring a minimum contrast ratio of 4.5:1 for standard text and 3:1 for large text is essential for WCAG compliance. Careful consideration of color choice dramatically improves usability and inclusivity.
