About Ultramarine (#0A058F)

The hex color #0A058F, commonly known as Ultramarine, is a deep, saturated shade of blue. Its origins can be traced back to the pigment derived from the precious stone lapis lazuli, which was highly valued for its intense color and rarity. Historically, Ultramarine was more expensive than gold and was often reserved for the most important figures in paintings, such as the Virgin Mary. Today, synthetic versions of the pigment have made it more accessible. In color theory, Ultramarine is considered a cool color, evoking feelings of calmness, trust, and stability. It is often associated with depth, wisdom, and intelligence. Its digital representation, #0A058F, signifies its specific position within the color spectrum, making it a versatile choice for graphic design, web development, and various artistic applications. This specific shade possesses a unique intensity that sets it apart from lighter or more muted blues.

The hex color #0A058F, also known as Ultramarine, presents some accessibility challenges, particularly in text-based contexts. Due to its dark nature, it necessitates careful consideration of contrast ratios to ensure readability for all users, including those with visual impairments. A light color should be used for the foreground text. The Web Content Accessibility Guidelines (WCAG) recommend a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text against its background. When using #0A058F for text or interactive elements, ensure sufficient contrast with the background color. Tools like contrast checkers can help verify compliance with WCAG standards. Furthermore, avoid relying solely on color to convey meaning, as this can exclude users who are colorblind. Providing supplementary cues, such as text labels or icons, can enhance usability and inclusivity. Proper attention to these accessibility considerations will ensure a more inclusive and user-friendly experience for everyone.
