General Information about Ultramarine

Ultramarine, represented by the hex code #040A94, is a deep blue color with a rich history. Originally derived from the gemstone lapis lazuli, ultramarine has been prized for centuries for its vibrant and intense hue. In art, it was historically one of the most expensive pigments, reserved for the most important figures and details in paintings, particularly the robes of the Virgin Mary in Renaissance art. Today, synthetic ultramarine is widely available, making it more accessible for various applications. In color theory, ultramarine is considered a cool color, often associated with depth, stability, and trust. It is frequently used in branding to convey a sense of reliability and sophistication. Its high chroma makes it a visually striking color, suitable for both digital and print media.

The color #040A94, a deep ultramarine, presents some accessibility challenges, especially when it comes to text and background contrast. When using this color for text, it's crucial to pair it with a very light color, such as white (#FFFFFF) or a very pale yellow, to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text. Using online contrast checkers is highly recommended to verify compliance. When using #040A94 as a background, avoid placing important information or interactive elements directly on it without careful consideration of contrast. High contrast icons or buttons can improve usability. It's also advisable to provide alternative color schemes or themes to accommodate users with visual impairments or color blindness. Remember to test designs with different color vision deficiencies to ensure inclusivity.
