#01049A

General Information about #01049A

The hexadecimal color code #01049A represents a dark shade of blue, specifically classified as ultramarine. In the RGB color model, it consists of 0.4% red, 1.6% green, and 60.4% blue. This significant dominance of blue is what gives the color its characteristic deep blue appearance. Ultramarine is traditionally associated with royalty, wisdom, and trustworthiness, often used to convey a sense of authority and stability. In terms of color theory, #01049A has a low saturation and brightness, making it suitable for backgrounds or accent colors when paired with brighter, contrasting hues. Its dark nature implies a formal and serious tone, and is thus well-suited to professional, corporate, or academic contexts.

The color #01049A, a deep shade of ultramarine, presents significant accessibility challenges. Its extremely low luminance value of 0.004 fails to meet WCAG (Web Content Accessibility Guidelines) standards for color contrast. When used as text, it requires an exceptionally light background to ensure readability for users, including those with visual impairments. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is essential. Therefore, pairing #01049A with light colors like #FFFFFF (white) or very light shades of gray is highly recommended. Using this color for interactive elements such as buttons or links requires careful consideration to ensure sufficient contrast in different states (hover, focus, active) to comply with accessibility regulations and provide a positive user experience.
