General Information about Ultramarine (#18019A)

Ultramarine, represented by the hexadecimal color code #18019A, is a deep, rich blue color reminiscent of the pigment derived from lapis lazuli. Historically, ultramarine pigment was highly prized and expensive, making it a color reserved for royalty and important artistic works. In modern color theory, ultramarine is considered a cool color, often associated with feelings of calmness, stability, and intelligence. Its deep hue lends itself to uses conveying trust and authority. In digital applications, #18019A can be used to create a sophisticated, professional aesthetic, although care should be taken to ensure sufficient contrast with text and other elements for accessibility.

The color #18019A, also known as Ultramarine, presents some accessibility challenges, especially for users with visual impairments. Its dark nature means it requires light-colored text for sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When used as a background, pairing #18019A with white or very light shades of yellow or green can improve readability. However, it's crucial to test the color combination with accessibility evaluation tools to ensure compliance. Avoid using this color for critical information if contrast requirements cannot be met. Consider providing alternative color schemes for users who may need them.
