Ultramarine

#180593

General Information about Ultramarine

The color #180593, also known as Ultramarine, is a deep, rich shade of blue that sits towards the violet end of the spectrum. It is a color often associated with royalty, intelligence, and depth. Historically, Ultramarine was derived from the precious stone lapis lazuli, making it one of the most expensive pigments used in painting. During the Middle Ages and Renaissance, it was highly valued by artists and reserved for the most important figures in paintings, such as the Virgin Mary. Today, synthetic versions allow for broader and more affordable use of this color. In color psychology, Ultramarine evokes feelings of calmness, trust, and authority. Its intensity can make it a powerful choice for branding and design, conveying a sense of sophistication and prestige. However, its darkness requires careful consideration to ensure readability and accessibility.

The hex color #180593, also known as Ultramarine, presents some accessibility challenges, particularly in web design. Due to its dark nature, text rendered in this color on a white or light-colored background may provide insufficient contrast for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. It's unlikely that #180593 will meet these ratios against many common background colors. To improve accessibility, consider using #180593 for larger graphical elements or pairing it with much lighter text colors, such as white (#FFFFFF) or very light grays. Employing contrast checking tools during the design process is essential to ensure compliance with accessibility standards and provide a better user experience for everyone, including those with low vision or color blindness. Also avoid using this color for interactive elements without proper contrast, as users may struggle to identify them.
