General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #051496, is a deep and intense shade of blue. It is named after the pigment originally derived from lapis lazuli, a semi-precious stone. Historically, ultramarine was highly valued and expensive, making it a pigment reserved for important commissions, like the painting of the Virgin Mary's robes. In modern color theory, Ultramarine is considered a cool color, often associated with traits like calmness, depth, and stability. In digital applications, it can evoke feelings of trust and security. However, its darkness means it should be used thoughtfully to ensure readability and accessibility, especially in text or interface elements. Understanding its historical significance and psychological associations helps in effectively using Ultramarine in various design contexts.

The hex color #051496, also known as Ultramarine, presents significant accessibility challenges, particularly in web design. Its very dark hue results in low contrast against lighter backgrounds, making text and interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Ultramarine often fails to meet these standards when paired with common background colors like white or light gray. To improve accessibility, consider using a much lighter color for text or interactive elements on an Ultramarine background. Alternatively, use Ultramarine sparingly, limiting its use to purely decorative elements where readability is not crucial. Tools like contrast checkers can help evaluate and improve the accessibility of color combinations.
