The hex color #1D0E8A, also known as Ultramarine, is a deep and rich shade of blue with a significant presence in art, design, and culture. Ultramarine is historically derived from the precious mineral lapis lazuli, making it a highly valued pigment in Renaissance paintings. Its name literally means "beyond the sea," referring to its origin from overseas. In the RGB color model, #1D0E8A consists of 11.4% red, 5.5% green, and 54.1% blue. This strong blue component gives it its characteristic deep blue appearance. Ultramarine is often associated with qualities such as depth, stability, and sophistication. Its dark, intense hue can evoke feelings of calmness, authority, and intelligence. Its rich history and visual impact make it a versatile choice for various applications, where a sense of elegance and trustworthiness is desired.

The color #1D0E8A, a deep shade of ultramarine, presents several accessibility considerations for web developers. Due to its low lightness value, it requires careful pairing with contrasting colors to ensure readability. Text rendered in #1D0E8A should ideally be placed against a background of a very light color, such as white or a pale yellow, to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio. When used for interactive elements like buttons or links, sufficient visual cues beyond color alone are crucial, such as underlines or borders, to aid users with color vision deficiencies. Furthermore, avoid using this color as the sole indicator of status or importance, as this could exclude users who cannot perceive it. Thoughtful design choices can mitigate these challenges and ensure an inclusive user experience.
