About Ultramarine (#170890)

Ultramarine, represented by the hexadecimal color code #170890, is a deep, rich blue pigment that has been prized for centuries. Historically, it was derived from the mineral lapis lazuli, making it one of the most expensive and sought-after pigments. The name 'ultramarine' literally means 'beyond the sea,' reflecting its origin from overseas. Nowadays, synthetic ultramarine is readily available, offering the same vibrant hue at a more affordable price. This color is often associated with royalty, wisdom, and spirituality. In art, it has been used extensively by master painters to depict the Virgin Mary, the sky, and other celestial elements. Its unique properties make it suitable for various applications, from fine art to industrial coatings.

The color #170890, a deep ultramarine, presents some accessibility challenges primarily due to its low luminance. When used as a foreground color against a white background, it may not meet the WCAG (Web Content Accessibility Guidelines) contrast ratio requirements for text legibility, particularly for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. To improve accessibility, consider pairing this color with lighter shades of yellow, white, or other high-contrast colors. Also, avoid using it for critical information or interactive elements without sufficient contrast. Employing tools that measure contrast ratios can help ensure compliance with accessibility standards, making your content usable for a wider audience. Adequate spacing and font sizing also play a crucial role when this color is used for text.
