General Information about Ultramarine (#10148A)

The color #10148A, commonly known as Ultramarine, is a deep, rich blue hue that evokes feelings of sophistication and tranquility. It falls within the blue-violet spectrum and is often associated with qualities such as depth, stability, and intelligence. Historically, Ultramarine was derived from the precious stone lapis lazuli, making it a highly valued pigment used by Renaissance painters for depicting important figures and scenes. Its name literally means "beyond the sea," referencing its origin from stones imported into Europe from Asia. Today, synthetic Ultramarine is widely available, retaining the same vibrant color at a more accessible cost. In color psychology, Ultramarine is believed to promote feelings of peace and clarity, making it a popular choice for branding and design applications seeking to convey trust and reliability.

The color #10148A, also known as Ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as text on a white background, or vice versa, it may not meet the WCAG (Web Content Accessibility Guidelines) AA standards for contrast ratio, making it difficult for users with visual impairments to read. A contrast ratio of at least 4.5:1 is generally recommended for normal text and 3:1 for large text. To improve accessibility, consider using #10148A with lighter shades of yellow, orange or green for text and graphic elements or pair it with a darker background to ensure sufficient contrast. Utilizing tools that evaluate color contrast ratios can help determine if the combination meets accessibility standards. Additionally, providing alternative ways to convey information, such as using descriptive text or icons, can enhance accessibility for all users.
