About Ultramarine (#1909AB)

Ultramarine, represented by the hex code #1909AB, is a deep blue color with a rich history. Originally derived from the precious mineral lapis lazuli, Ultramarine was highly valued as a pigment for centuries, often reserved for important works of art, particularly in religious paintings. The name itself translates to 'beyond the sea,' reflecting its origin from pigments imported into Europe from overseas. In modern color theory, Ultramarine is considered a cool color, often associated with feelings of calmness, depth, and stability. It is used across various applications, from digital design to fashion, due to its versatility and aesthetic appeal. The color's unique undertones make it a compelling choice for designs seeking a touch of elegance or sophistication.

The color #1909AB, also known as Ultramarine, presents several accessibility considerations for web developers. Its dark hue means that sufficient contrast with text and other foreground elements is crucial. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. White or very light colors work best as foreground colors on an Ultramarine background to ensure readability. Furthermore, avoid using Ultramarine as the sole indicator for interactive elements; always provide additional cues like underlines or icons. Screen reader users rely on proper semantic markup, which should be implemented regardless of the color scheme. It is advisable to test color combinations using accessibility tools to verify compliance with accessibility standards and to cater for individuals with visual impairments.
