#140A8E

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #140A8E, is a deep, vivid blue color historically derived from the precious mineral lapis lazuli. This pigment was highly valued for its brilliance and permanence, making it a prized color among artists throughout history. Today, synthetic ultramarine provides a more accessible and consistent alternative while retaining the original's rich hue. Its name, derived from Latin, literally means 'beyond the sea,' reflecting its origin as an imported pigment. In color theory, ultramarine is associated with depth, stability, and tranquility, often used to evoke feelings of calmness or sophistication. Its usage spans across various creative fields, from painting and design to branding and fashion.

The hex color #140A8E, also known as Ultramarine, presents significant accessibility challenges, particularly in text-based contexts. Its dark hue results in very low contrast against standard white backgrounds, making it difficult for users, especially those with visual impairments, to read text rendered in this color. To improve accessibility, consider using a much lighter color for text or pairing it with a very light background. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to meet WCAG (Web Content Accessibility Guidelines) standards. Tools like contrast checkers can help determine if color combinations meet these guidelines. Avoid using this color for critical information or interactive elements without careful consideration of its impact on usability for all users.
