General Information about Ultramarine

Ultramarine, represented by the hex code #100394, is a deep blue pigment derived from the mineral lapis lazuli. Historically, it was highly valued and more expensive than gold, making it a pigment reserved for significant artistic and decorative purposes. The name "ultramarine" literally means "beyond the sea," reflecting its origin from minerals imported into Europe from overseas. In the RGB color model, #100394 is composed of 6.27% red, 1.18% green, and 58.04% blue. It falls within the blue color range, known for its association with tranquility, depth, and stability. This color continues to be used in various applications, from fine art to modern design, due to its rich hue and historical significance. In modern color theory, it is important to consider its contrast with other colors for optimal visual appeal and accessibility.

The hex color #100394, a deep shade of ultramarine, presents specific accessibility challenges, primarily due to its low luminance. When used as a background, sufficient contrast is crucial to ensure readability, especially 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. Combining this color with light hues like whites, creams, or light yellows can help achieve this contrast ratio, making the content more accessible. Conversely, pairing it with dark colors should be avoided, as it can render text illegible. Designers should also consider providing alternative color themes or allowing users to customize colors to meet individual accessibility needs. Using contrast checking tools during the design process is highly advisable to verify compliance with accessibility standards and ensure a positive user experience for everyone.
